Maybe I am wrong, but Dave you said you deleted your account. Are you sure that is your account, if it was shouldn't it resolve to your _username_ you chose?

> http://www.facebook.com/dave.winer

The account Ben showed doesn't seem to be yours.

http://graph.facebook.com/100002526165063 (no username showed here)

whereas

http://graph.facebook.com/dave.winer (false i.e. gone)

Unless Facebook releases usernames after deleting accounts (or you remember that this is indeed your Facebook ID) I think these are all different accounts. There is also another http://www.facebook.com/profile.php?id=100001554391855 which as well does not show your username.
