Move away and support smaller upcommers.
With trading on gox you make it harder for new exchanges to get established. Support the newcomers.
Great point - there are good exchanges out there, like
Bitstamp and
Kraken 
I've always found Bitfinex incredibly good, more features and better support than MTGox.
The issue i had with MTGox was that it took forever to withdraw money from them. I gave up waiting after 5 months, after all $1200 now is much more useful than $1500 that never arrives.
