I thought for an instant this meant he'd joined Google, but no, he's still teaching in Colorado. I guess it's one of his former students who is now a Googler.
Anyway, while bouncing around the net I remembered that I particularly liked John's mention of a professional award he received in 1996:
A check for $2.56 from Don Knuth, 1996
I can't remember exactly the circumstances, but of course John was a recipient of one of the famous Knuth Reward Checks.
Though I see that Knuth is no longer issuing those checks.
