Just my two satoshis. We should focus on getting on two recognizable exchanges with decent volume:
Mintpal and/or
Cryptsy.
This quote from
CryptoScribe is relevant. The article's title puts it: "PREMATURE MULTI-LISTING DESTROYS NEW COIN PRICES"
Contrary to popular belief, having your new coin of choice listed on several exchanges is NOT a good thing for most of the community. What it typically leads to is a rapid price decline....Listing a new coin on multiple large exchanges is a bit like jumping on a baby horses back two hours after it has been born and expecting it to gallop off into the sunset with you sitting happily atop it. You are going to break the coins back.
