gox should have mentioned 0 fees earlier, the earliest i heard of this was today in an email from them (i guess like everybody else), one day after it's already started. if they had made it more public i expect there would have been massive fluctuations as people who want to get in would be that much more inclined to buy given that they would have gained an extra 0.6% btc, and the opposite goes for traders that want to get out (gaining 0.6% more fiat).
this is common sense, expect volatility
Your "common sense" contradicts my experience. Also, the email in my inbox is dated 11-28.
well ya bitcoin is unpredictable, so just because something should happen doesnt mean it will,
but do you agree with what im saying? lower fees means more profitable transactions, gives people more incentive to trade
