With all this bad news and lag surrounding MtGox, why haven't people been leaving? Is it fear of lower liquidity? Chicken-or-egg problem? Catch-22? (all the same thing I believe)
It may be the fact that people have a lot of faith in Bitcoin. And since Mt.Gox can't pay out $'s at the moment they are just holding on to their BTC instead.
MtGox can pay out US$'s at the moment via wire transfers.
This is the normal way of making large international payments.
