Sorry, running a bit late with this one. Flock – The Social Web Browser works with Windows, Mac AND Li
nux, so something for everyone here. It is specifically desiged to really integrate into the social networking sites like facebook and make your browsing experience “fast, convienent and fun!”
It is built on the Firefox technology and the current beta version is based on firefox 3. For those that use the web a lot for networking with people, shareing photos, using a web based email account then Flock is well worth considering.
Something I like is that Hotmail works better in Flock that it does in Firefox, so if you like your hotmail or live account but don’t like Internet Explorer then download Flock for free and see what you think 
Let us know if you use it…what you think…etc
