DownloadSquad’s take on Flock2.
Flock 2 is here, continues to underwhelm – Download Squad

It isn’t too bad. I have discontinued using Flock a few days after its initial release, it was memory hungry. Flock2 seems to do a better job, and i like some of the new social features, media streams, webmail checker etc.
Omnibar would be a good addition.
Overall.. Thumbsup!
