yeah cryptsy and https://poloniex.com i've seen many good coins hit their exchange and plummit.
i tweeted to university to just shoot straight for mintpal but they said they wanted smaller exchanges first.
really bad idea imo. you want an exchange where theres a lot of people with buying power.

the reason is miners want to make money on their coins, however those sites just don't have the buying power so those that mine end up listing it lower and lower to at least get something in return. the end result is murdering your own coin.
If i were to make a coin, i'd shoot only for mintpal right off the bat. no need to be on a bunch of exchanges when you can shoot for one and be done with it.
