Regarding this new "maker/taker" model, aren't those who provide the liquidity (i.e. those whose orders end up on the books) supposed to get a portion of the fee paid by those who take from the book?  This is the first time I've seen a "maker/taker" model described as both parties pay a fee with one just paying a lower fee.  This would seem to benefit Bitfinex a lot more than it would benefit traders, and I think it's going to end up creating a price divergence on this platform from other exchanges.   

A true maker/taker model (I think, and I'm no expert) should look like this:

Market makers receive 1/2 the fee paid by maker takers.
Market takers pay .3% fee (so Bitfinex receives .15%, and the market maker receives .15%).

This is how you "incentivize" being a market maker.
