OK, thanks everyone for your submissions, and now for the first round of feedback.
Some of them are a bit too "verbose", like #5, #6 and #7. The flying bits on #14 and #15 are nice, but they make the logo too noisy. #24 and #25 are too tall and also a bit too verbose.
What we like best so far is the "one row" submissions, like #1, #2, #18, #26 and #27. The logo needs to fit into many purposes, like on the top of a website (like we have currently on bitbucket.org), business cards, and possibly print (including stickers, etc.)
It would be nice if the font used was a bit more sophisticated and timeless, rather than something "playful" or standard (verdana, arial). We like Akzidenz-Grotesk (
http://en.wikipedia.org/wiki/Akzidenz_Grotesk) and Myriad (Pro also.)
In short, the bit metaphor is good, but needs to be refined a bit, same goes for the bucket. Neither of which are *required* to be in the logo. The slogan isn't required either, as we can add that ourselves.
