Hi!

While observing behavior of new exchanges I see 2 strategies: one successful and other is not.

1. The succsessful one is when new exchanges add new coins, which are not traded anywhere else. If somebody wanna to buy this new coin, he needs to create account exactly on this new exchange and it gives the new exchange the chance.

2. The unsuccsessful strategy is to add only well known coins which are already traded on cryptsy or BTER. But if user already can buy well known coin on cryptsy or BTER, why the hell he would register on new exchange? This strategy is stupid.

Now, after saying this, I'm suggesting you to add COMM coin to your exchange https://bitcointalk.org/index.php?topic=529481.0
It's 100% PoS coin, not simply copy-paste 5 min fork. And it's not traded anywhere.
