People coming from Twitter get crappy profile pics. Let's use Gravatar for this (which is what we're doing for those with GitHub accounts).

+1 from @ZoranJambor on Twitter.

+1 from me as well. Since GitHub is moving away from Gravatar, my profile picture will likely stop updating eventually until they add an API

It doesn't alone state that they're moving away from it, but you can no longer update your Gravatar email when editing your profile, so that seems to be the direction they're heading in.
