On: Atlassian acquires Trello for $425M

GitKraken looks promising, and introduces some new UI concepts (drag and drop merging, for example). It's still fairly young but could be a competitor.

I've been using Fork (git-fork.com), and it's fantastic. Similar UI to SourceTree on the surface, but more obvious in other ways. It's blazing fast, and the author is super responsive to requests and to make fixes.

Thanks for the recommendations, I'll check them out.
