Until bitcoin is at the point that most cities have a reasonable p2p trade market, this is the single largest fear I have with bitcoin.
The governments and big banks are going to fuck with the exchanges.
The pressure will grow as bitcoin picks up in popularity (threat level)
hopefully exponential growth will takeover linear force.
*edit*
Chances are this is just a small hiccup, gox has had and solved bank issues in the past.
Just saying that when issues like this come up, it hilights the fact that exchanges are a weak point.
