If you are referring to Polo or Bittrex, well I dont think they add many ETH tokens at all there. Most exchanges only work with Bitcoin-like coins for simple API integration, but I think the bigger issues is the lack of volume.
You cant just get into the big swimming pool instantly you first need to put your leg into every pond and slowly build up the trading volume until the big exchanges notice you.
Populous is on HitBTC too.
