Bitcoin is fine.  The tens of thousands of clients are still happily chugging away maintaining the distributed p2p block chain.

MtGox is just another business that takes Bitcoins.  If MtGox has problems, it is of no greater significance than if the Alpaca Sock guy were to have problems.

If MtGox can't provide a liquid market between dollars and Bitcoins, then others will fill the vacuum.

A month from now, we'll all look back on this and laugh.
