OK so 237573 and 237575 are now confirmed. My reward for 237575 went from 0.002-ish to 0.0003-ish. 237574 which was mined at almost the same time is still not listed ( http://blockchain.info/block-index/385234/00000000000000f595dabc67b09229d6cd93224da85c46415f5c782e09ab576f )

Luck has been with us, no doubt. I just wish technology were too.
