For me it boils down to:

1. Trust. I feel like I can trust Github. While that may not be true, the fact that the majority of the folks I know use github vs gitorious makes me feel trust, whether it's earned/valid or not.

2. Github's cost, for me, is negligible so I don't really bat any eyelashes at it. The $7/mo plan is perfectly fine for me.

3. Their UX is splendid. Every thing feels fairly intuitive me.

4. The social/community aspect I quite enjoy, though I do not participate as much as I should.
