StumbleUpon has introduced StumbleUpon App Discovery, a free beta feature of its Android app that suggests mobile apps based on users’ interests.

"Currently, discovering apps from the over 100,000 apps available in the Android Market is limited to keyword-based search features," said Garrett Camp, StumbleUpon CEO and co-founder.

"With StumbleUpon App Discovery, users can now find applications that are personally recommended to them and in many cases would previously have gone unnoticed."

StumbleUpon has launched a new version of StumbleUpon Video aimed at personalized video discovery. The company says its recommendation system has been "fine-tuned" to better personalize the viewing experience. 

StumbleUpon has finally released its mobile apps for the iPhone and Android.

"Think about all those times when your’e riding the bus, sitting at the airport gate, or waiting for friends, playing with the same mobile apps again and again," says StumbleUpon’s mobile apps team. "Now you can have the perfect boredom-buster: with StumbleUpon for the iPhone and Android, the best of the web is, literally, at your fingertips."

Earlier this year, StumbleUpon launched its new advertising system, which it said helps cost-effectively deliver advertiser content to targeted audiences, while increasing the opportunity for content to go viral. Since then, the platform has experienced some pretty significant growth.

The company announced today that it has experienced 20% growth since the launch in March, with about 2,000 active monthly customers running about 3,000 campaigns daily.

StumbleUpon announced that it has reached a new milestone. It has acquired its 10 millionth user.

The company broke away from eBay a little over a year ago. After that, it released its "web bar" feature as well as a new version of its Firefox add-on, a Chrome extension (which last month StumbleUpon claimed was one of the top 20 third-party extensions), and its content syndication service Su.pr.

StumbleUpon broke away from eBay a little over a year ago, and went back out on its own. The company has shared an interesting list of stats about StumbleUpon use since then.

Twitter generates nearly 10 percent of social media global hits to websites, according to new research from StatCounter.

The report found that Facebook is still the main source of traffic to global websites with almost half (48%) of social media hits followed by StumbleUpon with 25 percent.

Today is, for better or for worse, the last day many people will have off before heading back to work or school and resuming normal life.  And if you have lots of stuff to do, good luck.  But if you’re a bit bored – maybe still stuck at a relative’s house or just out of books to read – here are some of the "Most Stumbled Sites of 2009."

Earlier this month, StumbleUpon started showcasing their new homepage design, when they touted their “Google + Twitter” social search. Now they’ve gone through the rest of the site to make it more consistent (less customizable), easy to understand and streamlined.

Update: Starting today, all StumbleUpon users can access the new interface, according to the company.

A while back, StumbleUpon launched web stumbling, which allowed users to enjoy their StumbleUpon experience without having to download the toolbar, which was previously a requirement. If you’ve been a user of the service for a significant length of time, you’ve probably grown quite accustomed to that toolbar. Sometimes I forget it’s not just part of Firefox.

Facebook and Twitter have both been proven to be valuable sources of traffic to many sites, but another potential source that you might be overlooking is StumbleUpon. It is true that in the past, StumbleUpon has been presented as a traffic tool, but the results weren’t always what webmasters and marketers had hoped for.

StumleUpon announced today that it has launched a new URL-shortening service called Su.pr. The twist, however, is that this one is designed to help content creators actually increase their traffic with it. According to StumbleUpon, this is the first such service that does this.

A while back, StumbleUpon released web stumbling, which is the ability to use the service without having to download the toolbar that has accompanied it for years. The company has now announced some features that expand upon this. The StumbleUpon Team shares them with WebProNews:

First there were the acquisition rumors, then the acquisition. Then there were the sale rumors.

StumbleUpon is no longer part of eBay. Many have wondered why it was even part of it to begin with, but that pondering can now be put aside. The company has now been returned to its creators for an undisclosed amount.

The United States Marines, the Mormon Church, and the Korean Department of Tourism are all paying Australian-based uSocial to game Digg.com for them, according to a blog post at the Los Angeles Times.

Twitterer Veronica Belmont had discovered a Flickr page with an alleged upcoming toolbar from Digg that would potentially rival StumbleUpon.
