In case you didn’t yet realize it, tonight is Halloween. And if you didn’t yet realize it, maybe you don’t have plans yet. If not, as usual, the Internet comes to your rescue. If you’re stuck at home tonight for whatever reason, you’ll be able to load up Facebook and watch Heidi Klum’s Halloween party, streaming live.

Sure, it’s not as good as being there, but it beats doing nothing. And it’s being done with the help of Modelinia, a site devoted to capturing the lives of super models. Enticed yet?

Jed Stremel, Facebook’s Director of Mobile who has been with the company for four years, has resigned, according to a post on his Facebook profile. Stremel was charged with leading the company’s mobile strategy, and was previously involved in Business Development at Facebook.

Below is Stremel’s bio, taken from last year’s MobileBeat conference page.

Jed Stremel oversees Facebook’s mobile strategy transforming how individuals find and express information relevant to their life. Prior to Facebook, Jed played key partnership, business operations, and strategic roles at high-growth businesses. He spearheaded mobile initiatives for Yahoo! building the company’s efforts to empower seamless communications across SMS, WAP, Java, BREW, and other mobile technologies. At Tellme Jed managed distribution, promotion, and licensing relationships with leading online and telecommunications partners.

Nobody wants to be the kid who only gets invited to birthday parties because his mom calls up the other mom and asks. Everyone knows that only succeeds in making you even more unpopular.

Our guess is a fair number of the geeky employees at Facebook were exactly that kid. Which is why I’m sort of surprised that they’d think asking people to help out Facebook friends who don’t have a lot of Wall activity, or even many other friends. These people get mocked. Obviously.

We’ve all seen the messages under Suggestions on the Facebook home page. So and so only has two friends on Facebook, suggest friends for him? Others are urged to write on the Wall of unpopular users.

A reader writes to us today with a screenshot:

The Foo Fighters will be streaming a concert live tomorrow night on Facebook, direct from the band’s Studio 606 headquarters in Los Angeles. You can RSVP to the event here, and stream it live here beginning at 7 PM PST tomorrow. As with Facebook’s other recent video streaming events, users will be invited to update their status messages with their thoughts about the concert, which will draw in even more fans as they see the updates in their news feeds. The live video will be powered by Livestream.

Live concert streams seem to be a growing trend for the web’s most popular content and social sites. Last week MySpace streamed their Secret Show Weezer concert in San Francisco. And earlier this week YouTube streamed a U2 concert from the Rose Bowl in Pasadena, CA.

Facebook’s VP of Communications and Public Policy Elliot Schrage has posted an update to the site’s blog outlining a major rewrite Facebook is proposing for its Privacy Policy. Schrage writes that the new version eliminates the legalese of the privacy policy the company has used up until now, spelling out what the site is doing with user data in more explicit terms. You can find the proposed document here and the current privacy policy here.

The new terms are certainly easier to read, and they also contain some significant changes (including a couple Schrage doesn’t point out). One of these seems to indicate that Facebook may well be releasing location-related features soon (this is the first time any language related to location has appeared in any of Facebook’s policy documents, Facebook has confirmed) :

“Location Information. When you share your location with others or add a location to something you post, we treat that like any other content you post (for example, it is subject to your privacy settings). If we offer a service that supports this type of location sharing we will present you with an opt-in choice of whether you want to participate.”

Now that the dust is settling on the newly launched Google Music (if you don’t yet have it in your normal Google search results, you can use it here) that integrates LaLa and iLike/MySpace streaming music, all I can think of is this: What were Facebook and Ticketmaster thinking when they passed up the opportunity to acquire iLike?

MySpace is the big lottery winner here. They bought iLike for $20 million in August. What they got: a talented (literally) team that is starting to fill the executive ranks at MySpace, the biggest music application on Facebook, and, it turns out, a deal with Google that is now sending massive traffic flow directly to MySpace Music.

Our understanding from sources is that MySpace made an offer to iLike without knowing about the Google deal. Supposedly, since iLike was under NDA, all they knew was that iLike had a big partnership opportunity with some big company, nothing more. In hindsight the iLike deal looks smart even without Google. Add that in and it looks absolutely brilliant. I’m no fan of MySpace CEO Owen Van Natta, but I’ll give the man credit here.

This is a guest post by Nabeel Hyatt, Founder and CEO of Conduit Labs, which is the creator of Loudcrowd and other social games that help you experience music with your friends. His personal blog can be found at nabeelhyatt.com and he can be followed on Twitter @nabeel.

Yesterday, Facebook announced they are going to drastically alter the way applications can message users once again, likely throwing a wrench into every app developers’ growth rate. Hints of the coming turmoil appeared last week when Facebook changed the way feeds work. This caused enough worry that apparently Mark Pincus, Founder/CEO of Zynga, canceled his appearance at Harvard Business School so he could sit with his team and figure out what the impact would be to the viral rates of their massive hits such as Farmville and Cafe World. That’s not surprising, since getting posts in the feed is critical to continued growth, but the myopic focus on the “viral rate” by some in the industry has created an over-dependence on perhaps the wrong number.

Following its meeting with developers yesterday, Facebook announced some changes it will be making to its homepage. As expected, one of the biggest changes is an attempt to fight application spam.

Notifications from apps that you sign up for are being curtailed so that you can opt to only see those notifications that your friends explicitly send to you. That should get rid of all those random updates about Joey sending some virtual bananas as a gift to someone else you don’t care about. Facebook will also allow users to specify which applications may contact them via email and for what purposes, much like when you register for any Website and they ask you if they can send you marketing newsletters.

From Wikipedia: A tributary is a stream or river which flows into a main stem (or parent) river. Facebook wants every site on the web to be a tributary. And it wants to be the main river.

Today, amid the hoopla that Facebook was once again making changes to its site which may or may not make things more difficult for developers, something big was largely overlooked. To me, the more interesting thing was the new API Facebook briefly unveiled: The Open Graph API.

To say details are vague at this point is being overly generous. But, the key idea is in place, and was presented today. Basically, the Open Graph API is a way for Facebook to allow other companies, sites, services, etc to interact with Facebook without having to create a dedicated Facebook Page. Big deal, you might think — isn’t that what Connect is? Yes, to an extent, but it would seem that the idea here is to go way past that.

We’re here today at the Facebook Developer Garage being held at the company’s headquarters in Palo Alto, CA. The point of this rather large meetup for developers and the press is to talk about the future of Facebook’s Platform. As such, they’re calling this event the “Roadmap Edition.” As we noted earlier, big changes are expected to be announced today that will alter the way developers interact with Facebook’s Platform; this is D-Day.

Below find our live notes (paraphrased):

Mark Zuckerberg: Thanks for coming to our first ever edition of the roadmap developer garage. The Platform and Connect are quick becoming the most important part of our strategy today. We hope what we’re doing will help foster innovation.

Since its beta launch this summer, Brizzly has been hands-down one of the best ways to interact with Twitter. The web app puts a new and intuitive user interface over Twitter’s data, which allows you to do things like see pictures inline in your stream, and easily retweet anything with the click of a button. Today, Brizzly applies its magic to Facebook.

The new Facebook functionality for Brizzly, which should be live in the next couple of hours, puts the Brizzly look and feel over some of Facebook’s features. Within Brizzly, you’ll now be able to do Facebook status updates, wall posts, comments, and likes. For now, you won’t be able to post pictures or videos, but Brizzly will offer a way to display them inline that is arguably better than the way Facebook itself does it.

Facebook is holding a Developer Garage today at its offices in Palo Alto, and a number of new app policies will be formally announced. Some of the changes, though, are so dramatic that Facebook has briefed the bigger app developers in advance. And those developers are, to say the least, more than a little worried about the effect the changes will have on traffic and usage. One source we’ve spoken with estimates that the changes may drop usage on their apps by 70% or more (more on that below, some developers may use the changes to their advantage).

Like previous changes, Facebook is moving to clean up their user interface and try to get application spam under control. The changes will roll out over the next six months, we’ve heard.

Last week Facebook changed the way it publishes the news stream to users. For the last few months users have seen a constant Twitter-like stream of news from friends. Now the default view is algorithmic. A lot of applications (especially these guys) encourage users to add a status update every few minutes with what they’re up to – and when there was a constant stream of this stuff the apps benefited from all the extra traffic. That’s all muted now, and developers we spoke with say traffic and usage has declined 20% – 30% from just that one change.

And today Facebook will hit developers even harder. An even more lucrative traffic stream for apps comes from notifications – the pop up box in the lower right hand corner of Facebook that tells you when people leave comments or “like” your links and updates, etc. Today apps have free reign to publish into notifications without even telling the user. And they do it. A lot. When the changes go into effect, we’ve heard, apps will no longer be able to publish to notifications. There goes another 40% of traffic for the apps that use it heavily, say our sources.

Currently, if you want to share a Pandora station or song with a friend, you have to email it to them. Last time I checked, this isn’t 1994. Tonight, Pandora is joining the 21st century with the addition of simple ways to share stations and songs on Twitter and Facebook. And it’s further emphasizing a feature that no one seems to realize exists: Gifting Pandora stations.

On Pandora’s main playback pages you will now see a new set of buttons next to the traditional playback ones. These include a Twitter button, a Facebook button, a mail button, and a gift button. Clicking on any of those allows you to send the current station or current song you’re listening to via those respective services.

Foursquare and Loopt have put location-based social networks on the map, and have potentially created a viable business model as well. Now there’s a new kid on the block, called Stalqer, which best described as a Foursquare on steroids. The iPhone app, which will be free, should hit the app store in the next few hours.

In theory, Stalqer is very similar to Foursquare in that it tracks your and your friends’ locations and broadcasts this information via the application and through push notifications. But one of the key differentiators is the fact that Stalqer updates the location in the background, which Foursquare, and most other apps, don’t do at the moment. This is because the device does not allow third party apps to run in the background. But Stalqer has found a way to record your location without you having to actually open up the application. So how does Stalqer do it?

Facebook has just launched a new portal at peace.Facebook.com that highlights the site’s desire to promote “peace by building technology that helps people better understand each other”. The site appears to be part of a larger Peace dot movement that’s launching tonight, with the participation of some “impressive organizations” (we’re not sure who else besides Facebook is involved quite yet).

Peace.facebook.com is fairly simple at this point, with a handful of graphs and a widget that lets Facebook users share what they think of the site. The most compelling portion offers a series of graphs depicting “Friendships of Facebook”, which shows how many members of historically hostile groups are becoming friends on Facebook. These graphs include stats from Geographic, Religious, and Political pairings. There’s also a graph that shows the results of a daily poll conducted by Facebook on whether or not World Peace is possible in the next 50 years (over 35% of Columbians think so, but only 7% of users in the US are optimistic).

If you’re a computer science graduate a year out of college, there probably isn’t a celebrity you’d be more excited about knowing than Facebook CEO Mark Zuckerberg. So when he takes a minute to record a video with you to prove to your younger brother’s friends that you actually got a job at the company, it’s something you are pretty proud of. And the fact that Zuckerberg does this kind of thing is one of the reasons why Facebook wins. Watch the whole video with Dan Muriello here.

Orkut continues to undermine Google’s Data Liberation Front, whose singular goal is to “make it easier for users to move their data in and out of Google products”. Earlier this month the Orkut friend exporter, which makes it easy to export your friends’ contact information to a standard CSV file, was mysteriously broken due to a bug. The timing of the bug was more than a little suspect — Orkut has been hemorrhaging users lately in India and Brazil as people flock to Facebook, which takes advantage of Orkut’s friend export tool to help users make the switch. Now Julio Vasconcellos over at Armchairfounder has noticed how Orkut managed to fix their bug while still making it harder for members to switch to Facebook: the tool works, but it no longer includes your friends’ Email addresses.

Last week at the Web 2.0 Summit in San Francisco, Google’s Marissa Mayer took the stage for two reasons. The first was to formally announce the Google/Twitter search deal, but the second was the show off a new product: Google Social Search. The on-stage demonstration was interesting, but left a lot of questions unanswered. Today, the Google Labs experiment goes live, and we’ll get those answers.

Social Search essentially pulls in information from social networks to augment Google search results. But a major question is: What social networks get pulled it? While the experiment isn’t quite live yet, it would seem that from the video below made by Google’s Matt Cutts, Social Search, at least at first, will be able to include results from Twitter, FriendFeed, Picasa, Blogger, and Google Reader.

Twitter’s growth these days seems to be coming from abroad. ComScore data shows a 6.7 percent jump from August to September in worldwide vistors to 58.4 million (which translates to 949 percent increase from a year ago). The 20.9 million visitors from the U.S., in contrast, has remained flat since June.

These numbers do not include mobile or desktop app usage. But if Twitter hopes to become the first Web service to reach one billion users, it had better speed up its growth. Facebook, which is outgrowing Twitter in the U.S. even on a percentage basis, had an estimated 411 million visitors worldwide in September (up 5.5 percent from August). And Google is at 879 million unique visitors globally, according to comScore.

Earlier this month TC writer MG Siegler wrote a post called The Speed of Share, where he noted that sharing content to Facebook wasn’t as good an experience as it was for many of the various Twitter services like Tweetmeme. Today, that balance changes a bit: Facebook has just launched a new version of Facebook Share, which includes such niceties as a live counter that tells you how many times an item has been shared. We’ve just rolled it out to TechCrunch as well. Try it out above!

Along with the improved look of the Share Button, Facebook Share now offers publishers detailed analytics, allowing you to see how many times a link has been shared, as well as actions that occur on Facebook itself, like the number of comments and Likes it’s received as well as the number of times people have clicked on the link back to your site.
