But Mercurial itself wasn't (although it was written mostly in Python). I think this is a good example of taking the pragmatic choice (GitHub) over the ideological choice (Bitbucket).

BitBucket supports Git repositories...

That's mostly irrelevant. A lot of people are not using Github just because it supports git - the network effect is one of the key drivers in choosing Github.

Certainly but that wasn't on OPs list of reasons to use it :)

Looks like it was:

Where the people are would imply because of the social aspects.
