A section from the "Happy new year mail" I just got from BTCChina:
Maker-Taker fee structure. This new innovative fee structure will maintain a small 0.3% commission for traders, while rewarding market makers with a rebate. (The reward is effectively a “negative” commission, for market makers.) In summary, our company will still not be making money in commission revenue, giving all the benefits to our customers. By having a trading commission, this will reduce market volatility and reduce wild price fluctuations, which we believe is good for the entire Bitcoin market and ecosystem.
Not sure about the details yet, but that should help inceasing market depth, reduce the spread and thus make Bitcoin more attractive for actual payment. Hey, we may even be able to shift the focus away from day-gambling on this board and do what the board name implies: Speculation
