You people get so caught up arguing over every unimportant little nuance you've forgotten the point: mtgox is completely unsecure.  Do you really believe someone had 500,000 BTC in their account? Yeah right.  mtgox's account was hacked.  They're making tons of money but make no investment to fix their piss poor security.

As for this linux *bsd debate, I see a lot of people talking out their rear.  Reading wikipedia does not make you a security expert.  Running gentoo does not make you a linux expert.  And neither of these things qualify you to speak on the topic of network security.  *bsd is the first choice when security is the major concern, period.  Google bsd security if you don't believe me.
