Flock You !
Flock is a new variant of Firefox. In this case the idea is to stuff it full of "social software" such as Flickr and del.icio.us. It also has RSS integration that makes posting to popular browser-based blogs such as Wordpress and Blogger very easy. It looks interesting but as this is the first public beta release it is apt to come crashing down so it sure won't be the default browser right away. Download it from
http://www.flock.com/developer/ and provide some feedback to the developers so this puppy improves.
