Oooh, check out Mr. Five-digit-user-id over here (for the kids: an old /. reference).
The user name is their radio callsign, which you can look up in the FCC database. I don't know how much more attachment to a "real-world identity" you're looking for.
Ad-hominem much? It sure matters who the person in question making the statement is, but what's particularly relevant here, and to my comment, is that it's not easily discernible who they are.
