At first, Flock appealed to me in a purely superficial way. As you may have noticed, I’m a sucker for style, good design and pretty textures, and Flock certainly unites all of these features.
Fortunately, that’s not all there is to tell. Flock is based on Mozilla Firefox and was first released in 2005. Back then it may have been a little bit ahead of its time since social web was only in its beginnings. Recently however, Flock has enjoyed very positive media coverage and its popularity virtually exploded in the beginning of this year, reaching close to three million downloads and increasing the number of active users by 135% [Source via Wikipedia].
