+1, I love those interesting Stack Overflow (and Stack Exchange) posts that started to appear here every other week. I always learn something new/interesting from them. Thank you dcro :).

no doubt the SO question will soon be closed as "not a question" or "too interesting" or some other draconian response :(

They'll lock it to keep newbies away if nothing else, but I doubt it'll get shut down. This is a "good fit" for the Stack sites though - it's a direct question with one single direct answer.
