Shouldn't we be able to hop between associated sites more easily? If I am in the middle of perusing StackOverflow, and a great meta question occurs to me shouldn't there be a link say in the header, to take me there, since my accounts are linked, I've already authenticated via opeid, etc. I've done it by going to from stackoverflow->quesions to StackOverflow-> profile to meta->profile to meta->questions, but that's the long way around the barn.
