I traced one of my Gox deposits to this address
https://blockchain.info/address/1Nznb9Szo3Vx9njDUU5eVgqEe8YqiV5UwxInteresting pattern of activity - deposits of ~10-50BTC in round number amounts, lots of withdrawals of various small amounts. Perhaps coincidentally, activity stops on Feb 7 when Gox froze withdrawals. I'm guessing this could be one of their hot wallet address.
P.S. Is there some way to get blockchain.info to just show freakin' BTC and not mBTC? It's driving me nuts!
