I don't understand the benefit of gists. If they're full git repos, why not just use a normal github project? Having a pasteboard type gist makes me wonder things like, - Can a gist have multiple files in it? - What is a file inside a gist named? - Can I convert a gist to a normal project? - Can I convert a normal project to a gist?
