to stabilize price we would have to average it from various sources and probably display it directly in bitcoin client so people consider it as offcial.
I dont understand why even people know that mtgox is flooded with bots and speculants they still follow their price which is not natural at all.
The mtgox price is what you can buy or sell for on mtgox. It's a real price, nothing unnatural about it. Now if you are buying and you have a chance to buy for LESS than the mtgox price, by all means buy it for less, but it's a great guideline to avoid getting ripped off. And vice-versa, as a selling the mtgox price is a good baseline minimum for what you sell for, but it shouldn't stop you from selling for more if given the opportunity.
