Qwisk, which is launching today at the Real-Time CrunchUp, is an innovative new way to add a social twist to your browser. The site, which is a product of Y Combinator-funded company Socialbrowse, connects with you with your friends on Facebook and Twitter in real-time as you browse the web. We have 500 invites exclusively for TechCrunch users. You can redeem these invites simply by clicking here.

It’s important to note that Qwisk is a browser extension, not a plug-in to a browser. On the site’s page, you sign into your Facebook and Twitter accounts via Facebook Connect and oAuth. Qwisk will then add a sidebar to your browser that will show a feed of Facebook status updates and Tweets. You can also share any link or content to Twitter and Facebook from the sidebar itself.

Seesmic is having a huge week. The startup that develops Twitter and Facebook clients for the web and desktop just unveiled a native Windows client at Microsoft’s Professional Developer Conference earlier this week. At the Real-Time CrunchUp today, Seesmic is launching its first venture into the mobile space with impressive apps for both the Android and BlackBerry, which are now available for download here. This is a pivotal moment for Seesmic because the startup is now conquering all the mediums—web, desktop and mobile. I sat down with Seesmic’s co-founder, Loic Le Meur, to test out the apps.

The BlackBerry app, which works with the devices running OS 4.6 or higher, has a extremely sleek nice interface, which is optimized for BlackBerry users with all sorts of efficiencies. You can quickly change from different timelines, easily switching from your inbox, to mentions, to direct messages. Plus, you can monitor various Twitter accounts within one appp. When you send a Tweet, you can shorten a link via Bit.ly, and upload pictures or videos via yFrog. One compelling feature is the ability to email a Tweet to a contact directly from the Tweet.

Yesterday, Twitter changed its organizing question from “What Are You Doing?” to “What’s Happening?” But the new call to action might be better suited to Hot Potato, a startup launching right now at our Realtime CrunchUp. Hot Potato is releasing an iPhone app which lets you create a stream of conversations around events based both on your location and what your friends are doing.

Hot Potato is a micro-messaging app that organizes the conversation stream by events. For Hot Potato, an event can be anything that is happening right now: a basketball game, concert, party, street fair, buying a new car, or even just two friends on a bike ride. An event is whatever is happening that people want to share.

Today at the RealTime CrunchUp Salesforce CEO Marc Benioff took the stage to talk about the social enterprise with Erick Schonfeld and Steve Gillmor (he also introduced us to a new real-time Salesforce Chatter platform). Benioff has also signed a pair of copies of his book Behind The Cloud, which we’re going to be giving away to attendees of today’s conference.

To win one, just tweet out your favorite moment of the RealTime CrunchUp so far, and include the hashtags #CrunchUp and #Cloud in your tweet (#CrunchUp is the conference hashtag, and #Cloud will let us know who’s entering the contest).

We’ll announce the winners in this post later today, and you’ll be able to pick up your signed book at the front table. Obviously you’ll have to be present to win.

Today, during the Filtering the Stream roundtable at our RealTime CrunchUp, Seesmic’s Loic Le Meur asked why Facebook isn’t giving third parties access to their Friend Lists. Obviously, that’s a good question now that Twitter has starting giving third parties access to its Lists feature via an API. Normally, you’d expect a canned response along the lines of “we may do that in the future” or “we’re thinking about it,” but Facebook’s VP of Platform Bret Taylor was much more candid.

Taylor said that Le Meur’s request seemed “reasonable” and continued “we should do that.” “We’re not working on that. But we should be,” he continued. So there you go, done deal. Great. It would seem that soon, third parties should have access to the list filters that Facebook uses.

Salesforce.com co-founder and CEO Marc Benioff is sitting down with TechCrunch IT editor Steve Gillmor and TechCrunch co-editor Erick Schonfeld to discuss the socialization of the enterprise. Benioff recently unveiled his own social strategy for Salesforce: Chatter. Debuted at the company’s Dreamforce event, Chatter allows any company to collaborate in real time with a secure, private social network for their business. Content, applications and people will now have profiles, feeds and groups within the platform, enabling them to be connected via a unified stream. In addition, developers will now be able to tap into Chatter’s API to build social enterprise apps off of platform. While Chatter looks and feels like a social network for the enterprise, Benioff is quick to nix that moniker, preferring to call the platform a collaboration tool.

Below find my notes (paraphrased):

Everyone loves picture messaging – or at least, they love the idea of it. The iPhone carrying masses clamored for it, then celebrated once they got it by sending everyone pictures of their immediate surroundings and beloved pets before forgetting the feature exists. After the novelty wears off, it’s generally reserved for the occasions when there is genuinely something interesting to show. Need the wife’s advice on whether to buy the blue shirt or the green one? Picture message. Want to ask her out to coffee? You’ll probably stick with text.

FunMobility, a company thats been cashing in on cell phone media (like ringtones and wallpapers) since 1999, is looking to change that with FunMail, a service which they’re dubbing as “every-day picture messaging”.

At our RealTime CrunchUp event today in San Francisco, the first roundtable is entitled “Filtering the Stream: Getting Rid of the Noise.”

The panel is populated by a lot of big players in the space: Facebook, VP of Product Chris Cox, Google, Google Fellow, Amit Singhal, Seesmic, CEO Loic Le Meur, Futurity Ventures, investor/entrepreneur Edo Segal, CrowdEye, CEO Ken Moss, Microsoft, GM of FUSE Labs, Lili Cheng, Facebook, VP of Platform, Bret Taylor, MySpace, Chief Product Officer, Jason Hirschhorn, Thing Labs/Brizzly, CEO Jason Shellen, OneRiot, CEO Kimbal Musk, and Angel Investor Ron Conway. Our own Erick Schonfeld and Steve Gillmor are moderating.

Twitter has apparently come across the Holy Grail of advertising, and it’s coming soon. Today during his interview at the RealTime CrunchUp, Twitter COO Dick Costolo told the audience a bit about the company’s upcoming advertising business. Costolo was vague on the details, but he did make some promises: “It will be fascinating. Non-traditional. And people will love it… It’s going to be really cool.”

Costolo didn’t divulge many more details, though he did mention that it wouldn’t be tied into the site’s retweet feature. When TC editor Michael Arrington tried to clarify by asking if the ads would be integrated into the Tweet stream, Costolo said that “he didn’t say the ads would be mixed in with tweets”. But he didn’t say they wouldn’t, either.

Costolo closed out the topic by saying that the message he wants to send is that “Twitter will have an advertising business, ready in the near future, and available to partners.”

Opening our RealTime CrunchUp event today in San Francisco is Twitter COO Dick Costolo. Our own Michael Arrington and Steve Gillmor are sitting down with Costolo for a 30 minute conversation.

Twitter is one of the hottest players in the realtime field right now. And it has a $1 billion valuation, which has been the source of much controversy. Twitter also recently signed search deals with both Microsoft and Google.

Below find my live notes (paraphrased):

We’re here at the second TechCrunch RealTime CrunchUp in San Francisco, where we’ll be taking a deeper dive into realtime technology and where the streams are taking us. Kicking off the event is a conversation with Twitter COO Dick Costolo. And we’ll have much more real-time goodness coming your way throughout the day (see the agenda below). Watch the live stream of the event, powered by Ustream, here!

There are a number of real-time search engines in the space, including Collecta and OneRiot. Today, at the Real-Time CrunchUp, Infoaxe debuts its real time search engine.

What makes Infoaxe unique is that it doesn’t tap into streams from Twitter, Facebook, or Digg for content. Infoaxe’s search engine relies completely on attention data generated by the startup’s web history search engine.

Sorry for the short notice but I thought it might be fun to toast to Turkey Day and the launch of our our Gift Guide.

I’m teaming up with Cali Lewis of GeekBrief.TV for an impromptu CG meet-up in New York. We’ll be meeting at 7pm Friday at Heartland Brewery, 35 Union Square West, in Manhattan. We should be able to commandeer the back of the pub for our purposes.

Brizzly was first unveiled in private beta at our first CrunchUp event in July, so it’s only appropriate that today, the day of our next CrunchUp, it’s being opened to the public. Now, to be clear, the product is still technically in beta, but that’s only so the team at Thing Labs can keep experimenting with new ways to make Brizzly even better.

For those who have not had the opportunity to try Brizzly yet, it’s a web app that serves as a way to interact with both Twitter and now Facebook. It has advantages over Twitter’s regular website because it shows pictures and videos inline, and they actually did lists (which they called Groups) before Twitter. Now that Twitter has rolled out that functionality, Brizzly has integrated it. Perhaps more importantly, Brizzly also offers as one-click way to do the old-school way of retweeting. You know, the “RT” way.

Buying someone else a phone is risky business. Preferences vary, you’ve gotta get their carrier right… it’s a tough game. But if you’re down to make a gamble, we’re here to help. I’ve spent more time playing with new phones in the last year than anyone should ever spend with any phone ever, and have broken down my favorite offerings from each carrier by “Best Bet”, “Best Bet For Under $100″ (though it’s usually worth it to splurge), and “Best Bet for Business” for you Enterprisey folks.

Beauty, they say, is in the eye of the Wii-holder. The Charge Base IC is a $34.99 induction charging device for Wiimotes and looks like something out of a Frank Lloyd Wright sketchbook. The base sits firmly on the ground while sweeping cantilevered arms reach out to cradle your Wiimotes with magnets. It’s almost graceful, this amalgamation of clear and white plastic, the glorious sense of weightlessness, the architectural stability with just a touch of grandeur.

But darn it if the lights on this thing aren’t too bright.

Frustrated with the fact that Pandora does not provide its streaming service in Canada, Vancouver-based Jeff Anderson set out to build a community-driven Internet radio service of his own along with other music fanatics, and dubbed the project Listen.fm.

Currently still in private beta, Listen.fm is not going to be a ‘revolutionary’ service, says Anderson, but rather just a great place to listen to and discover new music that can legally be shared with others. The site has been in the works for nearly a year and should be launching in public beta some time next year.

Like a love child of eBay and CouchSurfing.com or craigslist, AirBnB lets anyone that owns space fit for accommodating travelers – be it a couch in a small apartment or the master bedroom of a 19th-century castle – post that space as a listing on its website and connect potential renters to its respective owners.

Once called Airbed and Breakfast in full, AirBnB aims to provide a secure online marketplace for these types of transactions and make people ‘travel like humans’ again.

Now the startup, which came out of Y Combinator’s winter 2009 class, is making it easier for people who share interests (e.g. photography) or have another connection with each other (e.g. alumni who’ve attended the same university) to share travel accommodation and recommendations thanks to the addition of Groups.

The public debut of Google Chrome OS today has the press abuzz over the potential of the new web-based operating system. And now that it’s open sourced, you have the chance to try it out for yourself. Unfortunately, most people aren’t ready to undertake the daunting task of actually taking Google’s recently open-sourced code and turning that into a bootable computer. So we’ve put together a step-by-step guide to doing this, for free, in around 15 minutes (depending on how long it takes to download the OS itself). No, this won’t get your computer booting Chrome OS natively (and frankly, you probably wouldn’t want to yet anyway). But it will get it up and running in a virtual machine using the free software VirtualBox, which is available for Macs, PCs, and Linux.

First, a few caveats: we didn’t create the Chrome OS build ourselves — it was downloaded from BitTorrent. In theory it could possibly have been tweaked by some malicious hacker to steal your Google account information (this is unlikely, but who knows). There’s an easy fix if you’re worried though: just go make a throwaway Gmail account, and use that to play around with the OS. Also note that because this is running in a virtual machine, you’re probably not going to be seeing great performance (like that 7 second boot time). But it’s more than good enough to get a feel for the OS for yourself.

We’re only about five weeks away from Christmas, so now’s as good a time as any to talk about (drum roll, please) e-books. Amazon kick-started the e-book market (with apologies to earlier e-book readers) with the introduction of the Kindle in the fall of 2007. Two years later, Barnes and Noble, IREX, and Sony announced new or updated e-book readers of their own.

The question becomes, which e-book reader is right for you? The truth is, they’re all very similar, so it should come down to what books their compatible book stores carry. Oh, and price, of course.
