New look

Yes, that's a new picture of yours truly in the sidebar -- a few years older than the last one, and with a lot less hair, thanks to the passage of time and a series of encounters with barbers around the world with whom I had few words in common. (Don't laugh: Can you say, "Just a trim, please," in Arabic?) It will grow back, but in the meantime, I figured you deserved something a little closer to my current appearance. I've posted a few other portraits from the last year; if you've got a strong opinion as to which do (or don't) belong on my home page, please let me know.
