How about you just untie yourself from MtGox. You've become a dog wagging tail and while I personally find nothing wrong with it, so long as you advertise very clearly your lack of funds when people deposit money (rather than when they attempt to liquidate), if you want to make people here happy, you're going to need to operate more like a dark pool.
Im glad im not the only one that sees this need..
I will launch a poll about that.
It wont be easy, but if you care about the community as a whole, mtgox needs competition, they are getting fat and lazy from your site, and its still a single point of failure.. Your the only one that has the potential volume!
