Maybe Mt.gox is after revenge from other Bitcoin exchanges? Mt.gox dropped from handling 80% [historically] of all bitcoin trades to only 25% today. Ultimately, this could be a business tactic by Mt.Gox to crash confidence in Bitcoin and possibly get customers back from other exchanges? Anyway, can't wait for
http://ex.nintencoin.com and other such exchanges to come online, so exchange fees can disappear for good!
