random gripe: if you use a different email on gravatar than on github, your gravatar wont show up on github.

it's becoming pretty standard, especially among techies, to have a unique email per site, so you can easily tell if a site is selling your address (or is a victim of a hack, like dropbox was).

I emailed them about it -- too bad!

You could register your different email again with Gravatar.
