Just thought I'd give the Flock browser a little love here since it hasn't gotten any yet here in our pages. Though I have just begun to test out Flock and will share more of my experiences, my initial impression is that it is cool and flexible.
Flock is an open-source, Firefox-based - and in their own words - "social Web browser". The idea behind Flock is to be the control center for one's Web experience. This includes photos and video, feeds, communication services, blogs and more.
Since I mention Flock here, of course it is available for Linux, now in Version 1.2.
Flock's Web site is http://www.flock.com.
