For what it's worth, I was able to withdraw BTC from my BitFloor account with no difficulty. Luckily I had no USD in my account (well, 34¢ actually). I imagine it will be a tense couple of days for anyone who had a large amount in there, but for the moment I see no reason to worry you won't get your money back.

Very disappointing though, IMHO this was the easiest exchange to use.
