Have you heard of the established exchanges of MTGOX and CAMPBX?
What do you offer that they do not? They have the traffic, they have the volume. Why would people even consider your exchange?
Facebook has lots of traffic that doesnt mean you can speak to Mark Zuckerburg. What proof do you have on the claim about traffic ?
Every exchange has different reasons one might want to use it. CryptoXchange is in Australia physically so why would I use an overseas exchange

We need more exchanges not less and if MT Gox gets shut down where else are you going to go ?
