Free accounts for students?
mdasen: I'd be in favor of it.  In fact, it's one of the reasons that I use Mercurial/Bitbucket (bitbucket.org - they allow you to have one free private repo no matter who you are).  Offering students a Micro plan probably wouldn't cut into profits too much and it will get them in the mindset of using git (rather than svn or hg or whatever).  Most people don't like learning new things when they're comfortable with one - get them while they're young.  You're the premier git host.  More git people means more money for you.
