Well Etherdelta sure isn't the greatest of the exchanges out there but it's still a good heads up for the coin and surely will give it a boost when it gets listed . Later on other exchanges will consider listing it if the coin start doing well.
People don't consider that a token get listed on etherdelta exchange as effort from the team, because it happen automatically. any ERC20 token can be trade on etherdelta. The team said that TRB will be listed on Gatecoin, hitBTC exchanges right after ICO. So they actually offered more options for us.
