Why have no other alt exchanges been set up? cryptsy is the only good one that is why they are screwed everyone is heading there.
Since the problems with Cryptsy have been dragging on with no real improvements, I've begun to explore Coinex.pw. The exchange rates on some of the coins have been comparable with some a little higher and some a little lower. The volume is nowhere near as high as Cryptsy, and it's in beta with a few quirks of its own, but it works.
