Assisted by the fact that I inexplicably haven't been able to see avatars since the site updated too.
My own avatar dissappeared into the ether back when everyone got free pub club or whatever.
It's the username that I generally associate with the avatar. I'm guilty of complicating that every so often though. I wonder if avatars were held to the same standards of a username if it would be easier.
I recognize people by usernames more reliably, but the avatar is what I get attached to so long as the user doesn't change it often.
I've kept mine the same since some user animated it for me in a March Madness thread in 2011 or something.
