I've been testing the Flock browser for over a year. The idea is brilliant. A browser that makes tapping into social networks and web services really easy.
I loved Flock when I downloaded it for the first time last year. Then all sorts of bugs appeared in versions. I thought Flock was going to go belly up.
BUT they focused... Flock 1.0 is a beauty. Flock is a feat of serious determination. I recommend it and in this video I show various aspects.
