The Official Juan Non-Volokh FAQ:

Q: Hmm; Juan Non-Volokh. What kind of name is that?

Q: That sounds fishy -- what does he have to hide?
A: His name.

Q: Oh, pretty please, we're soooo curious -- tell us who he is.
A: No.

Q: Ah, I've got it figured out: This is actually your own pseudonym, so you can post things that you'd be ashamed to see under your name.
