This week, the Flock browser exited their beta phase and have announced the release of the first 1.0 version of the browser. Originally an offshoot of Firefox, Flock is intend to be a "social" browser, coupling Internet browsing with social networking. About a year ago, we interviewed Flock and got an idea of what they were trying to accomplish.
While they didn't quite make their original release date of the end of 2006, they have worked hard to get it out and now it is available for download on Windows, Mac or Linux. You can read the press release in the comments section.
