Flock was launched in November 2007 and is growing fast. CEO Shawn Hardin projects that, with more than one million downloads to date, Flock will have tens of millions of users by 2009.

In honor of Earth Day, Flock recently launched a special edition of their popular browser with an unprecedented promise, to donate 10% of revenue generated from the niche browser's searches to charity; and after winning an award for community at SXSW, the charity will be selected by none other than the Flock community itself.

The People button turns the sidebar into a nifty way to track your social-networking accounts. Flock is the only way to go if Twittering, Facebooking, or YouTubing is how you spend most of your time online.

In partnership with Discovery Networks, New York Times, Yahoo, TreeHugger, Grist, Ecorazzi and AllTop, the Eco-edition comes pre-loaded with all the best environmental content and features from these varied resources.

If you find yourself racing around the Web to keep up with your pals on Flickr, Facebook, YouTube, Twitter and similar sites, there is a Web browser built with you in mind.

In conjunction with the release of version 1.1, Flock is making available what it claims are some pretty big usage numbers. They claim to have nearly three million downloads of the browser.
