I've gotta say...I tried TH when gox came back up but wasn't trading yet.

I'm quite finished with TH now.  Yuck.  They didn't mess with my data (so far as I know) but as a trading interface it's beyond weak.

Without a colossal rebuild, I don't see a lot of business moving permanently to TH.  Just my opinion as a small time miner/trader.  The level of skin I have in this game is pretty low.
