Someone has written a nice review of Flock beta 1. Flock is a web browser based on the famous Firefox browser, which works on all versions of Windows from Windows 98 on, as well as on Mac OS X, and Linux. Flock adds fun "social" features to the browser, like a word processor for blogging, photo-sharing, news-watching, news-reading, etc. Flock works on this site too. So does Firefox, for that matter. And Camino. All 3 of them use the same web page rendering core.
