Free Snail-Mail Holiday Postcard from Gmail

snail-mail holiday card on your behalf to a (U.S.-based) recipient of your choice. There are six Gmail-themed cards to choose from.

A kind gesture? A small test of a future Google service? A subtle nudge to get would-be Gmail users online? The Gmail team says it's simply a 'token of appreciation to our most enthusiastic fans.' My guess is that the offer will be up a week or less before they're overwhelmed by requests.
