Can we use non-gravatar avatars?
It would be great if we could upload a picture directly without going through Gravatar. I don't like the idea of a central place which ties all the websites I've ever been too and all the comments I've ever made, so I have deleted my Gravatar account (well as much as they allow me to delete anyway). However it means I can't have a SO profile picture anymore.
So if Stack Overflow could give us an option to manually upload our picture, that would be perfect.
