Apologies if I'm being completely out of line here by pointing out what I perceive to be small but not intractable problems. I'm on three medications right now, and one of them is booze.
When you're looking at the profile of a user who has accounts on every SO network, it isn't immediately obvious which box is for what site. The only differentiator seems to be the tiny icon to the left of the user's name.
Wouldn't it make a lot more sense to have a textual label for each box?
