I wonder how much the Dwolla chargebacks cost TradeHill. We find out TH is screwed out of a big chunk of money and suddenly they're not paying out and switching banks. I'd be surprised the dwolla stuff set them back that much but when it comes to Bitcoins it's hard to be surprised anymore.
I sure hope they can weather the storm as they have proven to be the most honest and forthright firm associated with bitcoin so far.
