My two cents: I like git-scm.com quite a bit. As for the logo, I think it's nice and simple, and based on experience I think that for every logo you'll find people who object to it. E.g. the red color of the log on git-scm.com looks great to me, while I dislike e.g. the color variation Felipe is using.

While we are at it, can I please get that bike-shed in turquoise with a hint of ocean blue mixed in?
