Somebody just posted a rant - http://stackoverflow.com/questions/6036325/whats-wrong-with-you. I thought I would check their profile and see what the fuss was about. Problem was, the post they're obviously upset about doesn't seem to be there. And now that the rant was deleted (as it should have been), it's not showing up either. http://stackoverflow.com/users/726359/themonster
I can see why we don't want deleted questions referenced in any of the usual places, but it seems like the user profile should be complete.
P.S. The rant started with a request to close their account, so the links I placed above as an example are probably worthless. The question still stands.
