The new browser wars on on. More than a decade after Microsoft killed off Netscape with Internet Explorer, competition in the browser market has never been stronger. Just last week, Mozilla released Firefox 3.5, which has now been downloaded nearly 14 million times. Earlier in June, Apple released Safari 4. In March, Microsoft introduced Internet Explorer 8, and Google came out with a speedier beta of its Chrome browser.

Some early data is coming in showing relative market share and how fast people are upgrading. If you look at the chart above from Statcounter, it indicates that since March Internet Explorer has lost 11.4 percent market share to other browsers.

Ever since OS. 3.0, the latest operating system for the iPhone, launched on June 17, prices among the top 100 apps in the iTunes App Store have been fluctuating wildly as developers push out apps taking advantage of all the new features in the OS. Some of the new features we are starting to see in apps include push notifications, turn-by-turn navigation, cut-and-paste, embeddable maps, access to external accessories, search within apps, and subscriptions.

Mobile app distribution service Distimo just put out its June iPhone App store report As you can see from the charts above, the average pricing among the top 100 paid apps was pretty steady until the middle of the month, when developers started to test different price points. The most popular price for an app remained $0.99, but the month of June saw more top apps priced at $1.99, $4.99, and $9.99 (the green bars on the chart above).

In the first 24 hours since its release yesterday, Firefox 3.5 has been downloaded more than 5 million times. (It took only a few hours to pass a million). That is certainly respectable, but doesn’t quite measure up to the mania that Firefox 3.0 set off last summer, when it achieved a “world record” 8.3 million downloads in a single day. Maybe we’ll have to wait for Firefox 4.0 to beat that record. But Firefox 3.5 might still beat the 11 million downloads Safari 4 got over its first three days of availability.

After four quarters in which venture-backed IPOs have been dead in the water, a handful finally poked their heads up in the second quarter. The National Venture Capital Association counted five IPOs during the quarter, including DigitalGlobe ($279 million raised), SolarWinds ($152 million), and OpenTable ($60 million). A total of $721 million was raised. Just for a little context, two years ago during the same period, there were 25 IPOs which raised $4.15 billion.

So don’t call it a comeback just yet. But any activity is a sign of hope. And this was the most active period since the fourth quarter of 2007. Will it keep building, or will IPO candidates duck their heads back under water?

If information is power, the first step to gaining power is to get the right data. The Obama administration is a big proponent of opening up government data and making it digitally available. Today at the Personal Democracy Forum in New York City, the government’s new chief information officer Vivek Kundra announced USAspending.gov, a new site which launched today that tracks government spending with charts and lists ranking the largest government contractors (Lockheed, Boeing, Northrop Grumman, etc.) and assistance recipients (Department of Healthcare Services, New York State Dept. of Health, Texas Health & Human Services Commission, etc.). There is also the Data.gov project, which is attempting to digitize government data and make it available in its raw form for citizens and companies to sift through.

While Kundra agrees in principle that all public government data should be online, he also cautions that the reality is government data sits in more than 10,000 different systems, many of them written in COBOL or are still locked in dusty paper archives. But at least the government is starting to tackle the problem. The government collects a wealth of data, and the more accessible it becomes the more transparent government itself will be (not to mention the opportunities to startups which can tap into this data to offer new services). The State Department is also using the Internet, and Youtube specifically, to reach out directly to citizens of other countries every time Obama or Hillary Clinton travel abroad. They record video messages to citizens of other countries, which are distributed in multiple languages. Call it YouTube diplomacy.

We’ve been a bit baffled by the system Apple has in place when it comes to ratings for applications in the App Store. Is it allowing apps with nudity? Not allowing them? Allowing them with a 17+ rating? We’ve talked to some developers willing to break their NDAs because they think the App Store approval process in general is messed up, and would like to see Apple do a better job handling it. So here’s how the ratings system currently works for the App Store.

The Ratings

When you go to submit your app through iTunes Connect, one of the steps takes you to a ratings matrix that you must fill out. This contains 10 questions listed under “Apple Content Descriptions.” For each of the 10 questions you must say “None”, “Infrequent/Mild”, or “Frequent/Intense.” Depending on what answer you give for each of these, the rating of your app in the upper right corner will change. These ratings go from “4+” to “9+” to “12+” to “17+” to “No Rating.”

That last one is key. If your app gets the “No Rating” label, a warning written in red appears underneath it stating that: “This content will not be sold via iTunes.” So what triggers such a rating? Well, not a lot. Basically, it comes down to the final two questions in the 10 question matrix. Let’s run through them in descending order:

LinkedIn has bolstered its position as America’s leading business social network by the month lately, with Germany-based Xing as the only company regarding itself a worthy competitor in the last few years. But now those days seem to be over - in the US and China, at least.

Today German newspaper Hamburger Abendblatt published an interview [GER] with Xing CEO Stefan Groß-Selbeck (who recently replaced founder Lars Hinrichs), and he revealed a couple of interesting tidbits of information about the future direction of his company (find a horrible, Google-translated version of the full interview in English here).

Talking in broad strokes, Groß-Selbeck said 3.5 million of the 7.5 million Xing members are based out of Germany, Austria and German-speaking Switzerland. This isn’t really that surprising, given the background of the company. But the interview also marks the first time a Xing representative publicly (albeit indirectly) admitted losing in the USA and China.

Of all the misguided schemes put forth lately to save newspapers (micropayments! blame Google!), the one put forth by Judge Richard Posner has to be the most jaw-dropping. He suggests that linking to copyrighted material should be outlawed.

No, Posner does not work for the Associated Press (which also has some strange ideas on linking). He is (normally) considered to be one of the great legal minds of our time. Posner is a United States Court of Appeals judge in Chicago and legal scholar who was once considered a potential Supreme Court nominee. He is someone who should know better.

Just like every other major Website, Google was inundated with people looking for news about Michael Jackson yesterday. Above is a chart showing the volume of search queries for the deceased pop star. Searches peaked right around 3 PM PDT, as people all over the world were trying to find out information about his passing.

More details on the Google blog.

One of the hottest areas of search right now is real time search, which attempts to find results based on what is happening right now. Twitter’s search engine fast becoming one of the key ways to navigate the service and discover what people are thinking about any subject at any given moment. Facebook is testing out ways to let you search your personal stream. Google is waking up to the challenge as well (Larry Page is particularly concerned with keeping up).

Every week, it seems, a new startup launches tackling real time search from a different angle. (Collecta, One Riot, Scoopler, Topsy, Almost.at, Tweetmeme, CrowdEye, Omgili, to name a few).. They are trying to apply real time search to all the different streams of information flowing over the Internet right now: Twitter, Facebook feeds, Digg submissions, blog comments, RSS feeds, Flickr photos, YouTube uploads, shared links on bit.ly and elsewhere. The list keeps getting longer every day.

There is something about human nature which makes us want to prioritize information by how recent it is, and that is the fundamental appeal of real time search. The difference between real time search and regular search didn’t really crystallize for me until I had a conversation with Edo Segal, who sold his real time search company Relegence to AOL a few years ago and holds three patents on the subject. “Real time taps into consciousness,” says Segal, “search taps into memory. That is why it so potent. You experience the world in real time.”

For those of you who need more information widgets in your life, Netvibes is adding widget recommendations to its homepage service. It just started rolling this feature out today, and all Netvibes users should see it within the next two or three days. It looks at all of the information widgets on all the pages and tabs in your account, compares that to other members with overlapping taste, and suggests content they have that you don’t.

When users click on the “add content” button on the top left, a “Recommended” option will appear below the widget search box. Clicking on that will generate 12 new widget recommendations across nine categories of interest: news, sports, business, technology, entertainment, shopping, lifestyle, games, and travel.

When I tried it, most of the recommendations were for news, since the way I use Netvibes is to scan dozens of blogs and news feeds on a single page.

Kevin Marks, a social force within Google and one of the main drivers behind its recent social efforts (including OpenSocial, its Social Graph API, and Microformats) is leaving the company. He announced his departure today on his blog. Marks was an evangelist to other engineers outside Google, his official title was Developer Advocate. For many Web developers outside Google, he has been the public face of its social efforts in recent years.

Contacted by phone, Marks says he is working on a bunch of things “related to the social Web” and “activity streams,” but declined to get into specifics. Asked why he is leaving Google, he responds that his work is pretty much completed: “Over the last two years, we have built out the infrastructure for the social Web. Now it is time to build things on that infrastructure.”

As Microsoft tries to take away market share from Google with its new search engine, Bing, it is battling Google feature by feature. One feature where Microsoft seems to be edging out Google is with displaying recent search trends. This may not be a major feature, but it shows a weakness in Google’s armor.

On Google, you can create charts showing the popularity of keywords using Google Trends. On Bing, this feature is called xRank. For all but the most popular terms, Google Trends shows a lag of about three days, whereas xRank shows data that is up to date as of today.

For instance, you might want to see how many people are searching for Ricky Barnes, the golfer who came out of nowhere to lead the U.S. Open this weekend. Bing’s xRank shows the spike in interest you’d expect to see over the past two days, whereas Google Trends shows no data whatsoever.

As the world watches the violence and post-election protests escalate in Iran, startling images from the streets of Tehran are disseminating through various social media. Many of them are tagged #iranelection, a hashtag which started on Twitter but is spreading to Flickr and elsewhere.

Since it is difficult to find photos in the sea of Tweets using the same #iranelection tag I’ve been using Twicsy, an image search engine for photos posted to Twitter which we wrote about yesterday. If you search “iranelection” or “tehran iran”, dozens of images from the protests will pop up. (Photos after the jump).

In honor of the iPhone 3G S launch today, I thought I’d point out a humorous little deal circulating around the web. Apparently, you can use Microsoft’s Cashback program that it runs through its search engine (and now through Bing), to get a healthy 35% discount off of the device.

Depending on your eligibility for AT&T’s subsidy (more on that here), that means you can get an iPhone 3G S 16 GB for $129.35, the 32 GB version for $194.35. Or, perhaps even better, an 8 GB iPhone 3G for $64.90. Yes, you can get a new iPhone for $65 — thanks to Microsoft. Crazy.

Here’s is a full rundown of how to make it happen:

One month after the launch of the App Store in 2008, Apple had seen over 60 million downloads of its apps. The Palm Pre hasn’t been out for a month yet, but it’s about halfway there, so how close is it to that number? Not close at all. Not in the same ballpark. Not even in the same city.

Palm’s App Catalog has seen roughly 666,000 app downloads in its first 12 days, according to the mobile analytics firm Medialets. And what’s worse is that the download momentum is slightly slowing down since the initial launch. So don’t be too surprised if one month after the launch, the App Catalog downloads are near 1 million. Yes, 1/60th of what the App Store was doing last year.

Never underestimate the power of first-mover advantage, especially when being one of the first movers gets you bought by Google. Back in August, 1999, Pyra Labs launched Blogger. LiveJournal had launched six months before and Open Diary in October of the previous year. But it was Pyra Labs which was acquired by Google in February, 2003, and the rest was history. Now, nearly ten years later, Blogger is still the dominant hosted blogging platform. In May, 52 million individual people from the U.S. visited a Blogger blog, almost twice as many as the 28 million who visited a blog hosted by Wordpress.com (comScore). Six Apart properties, including Typepad.com, attracted 14 million.

Millions of bloggers still use Blogger because it is easy. However, Wordpress.com is making steady gains and growing its aggregate audience in the U.S. at more than twice the annual rate of Blogger (40 percent versus 14 percent). These numbers don’t count all the blogs that host Wordpress on their own servers, such as Techcrunch.

One thing Yahoo has been very good at over the past year is closing down services. Today brings news of another one shutting down: Yahoo Gallery. Come July 14, it will be no more.

Yahoo Gallery was a project that never left beta testing. It was intended to showcase cool applications that were built using Yahoo’s various services and APIs. And while it was a decent idea as a way to show off cool things like Flickr apps, it never really took off. Here’s Yahoo’s explanation message about the shuttering:

We’ve received numerous reports of Amazon Associate members in North Carolina receiving emails stating that Amazon is going to have to discontinue the service there due to a pending change the in state’s tax structure. Sometime in the next two weeks, Amazon expects that it will be terminating the service for all North Carolina residents. That will be very bad news for a lot of people who rely on Amazon’s popular affiliate sales program as a source of income.

Here’s the full email:

So, after a tidal wave of criticism from the iPhone early adopters, AT&T is doing the right thing — kind of. Today, AT&T issued an update to its policy regarding the iPhone 3G S upgrade price. Previously, only those existing customers who were eligible for a new phone subsidy (typically those within a few months of their two year contract expiring) would get the best price for the device. That meant no current iPhone 3G owners were getting it because that device is only 11 months old. But now, AT&T will offer the best price to some iPhone 3G owners — but which ones? Basically, it looks like those with the most expensive contracts.

“We’re now pleased to offer our iPhone 3G customers who are upgrade eligible in July, August or September 2009 our best upgrade pricing, beginning Thursday, June 18,” AT&T writes. But don’t be fooled, that’s far from everyone.
