I bet that the same problems with mtgox are with other exchanges.
Beware were you put your money because exactly like mtgox other exchanges will have issues paying their customers.
Some may be at risk, and I don't believe all exchanges are, but it is prudent to withdraw your coins just in case. There are one or two exchanges that I believe are extremely healthy and may use them more often in the future.
(Don't ask me which, I don't want to be responsible when they die too)
