Flock released Version 2.0 Final a short time ago.
The 'social' web browser now uses the latest Mozilla engine (used in Firefox 3.0.3) and continues to integrate a variety of social networks and micro-blogging platforms.
For some, Flock will be enjoyable and potentially make life 'a little easier'. The browser consolidates your contacts in a 'people bar' and alleviates the necessity to open separate tabs in Firefox.
Digg, Facebook, Flickr, MySpace, Pownce, Twitter, YouTube, Blogger, Photobucket, Picasa(web), Piczo, Blogsome, Livejournal, Typepad, Wordpress(.com), Xanga, Delicious, Magnolia, Gmail, Yahoo Mail and AOL Mail are all integrated into this version along with the familiar 'media bar' for quick photos and videos, as well direct blogging to various platforms.
It would be nice to see identi.ca, socialmedian, seesmic, a few others and (are you listening Evan?? :) Friendfeed included as well.
