OTOH, bitbucket has free private hosting and git doesn't (AFAIK). I think that is a crucial point for a beginner who is just learning to code and doesn't want to a) pay money, or b) have his ugly code be visible to the world.
Don't be afraid to show your code to the world. Better yet, paste some in a pastebin and ask for tips in an IRC channel: it'll make you a better developer.
It's often hard to get people on IRC to actually respond to a pastebin more than 15 lines long. IRC is good for "Can you tell you why my function is busted," but not so much for "How can I improve the architecture of my 500 line app". (The usual first answer to that, BTW, is "Reduce your 500 line app to 300 lines without removing any functionality")
