For the compiler, the barriers to contribution are probably elsewhere, but for the libraries, I'm sure, it would lower the barrier to entry. For example, to fix some documentation, I personally would never bother to create a patch file and attach it to some Trac ticket (where I first have to create an account). In contrast, a pull request on GitHub is a matter of a few clicks.


PS: Anybody who doubts this needs to post their GitHub account name, so we can check that they actually ever used GitHub properly ;)
