Developers of a “social” Web browser called “Flock” have released a new test version. Like its predecessors, the Flock 2 beta uses building blocks from Mozilla, an open source community in which thousands of people collectively develop free products. The newest version of Flock incorporates improvements from Mozilla’s Firefox 3 browser, which is scheduled for release Tuesday. Flock emphasizes the social aspects of the Web with features like better integration with news-recommendation site Digg, online hangout Facebook and group-messaging service Twitter.
