Bitbucket is great, but also check out SourceTree, their git / Mercurial client http://www.sourcetreeapp.com/
Interestingly, I recently talked to someone in an interview setting who got asked a question about git, and as soon as the interviewee started saying, "Typically I use SourceTree," the interviewer's demeanor turned sour on asking any further version control questions.
Just because someone uses a GUI for version control doesn't mean they don't understand it... I prefer the way SourceTree makes it very easy and visual to stage portions of a file, and the always-displayed tree makes it very clear how different branching and merging operations are going to happen.
Seemed like some weird attitude against a GUI source control tool... especially one specifically well-designed for a Mercurial or Git workflow.
Weird. I haven't worked in a team where people used the command line for bread-and-butter source control since 1996 or so. IME it's harder (not impossible, but harder) to screw things up with fat fingers using a GUI, and pretty much every time you use SCM you're going to want a good diff view anyway. (We tend to do basic paired code review at commit time.)
It's kind of tragic; I don't think anyone would describe the git UI in flattering terms, but now that it's become a 'pons asinorum' for geek machismo it's almost impossible to replace it.
And I agree, SourceTree is lovely.
- new branches (I find the syntax tedious for some reason, and I like to see where I am in the tree, so I'm already looking at SourceTree's interface when I'm branching) - deleting remote branches (see above about syntax) - awesome diff visualization for past commits and current work
Everything else I do on the command line, because SourceTree requires just a few too many clicks for my liking. It's a shame the terminal can't have a nice diff interface like SourceTree's, otherwise I'd probably be full terminal.
