I don't really know how to make it any clearer. Twitter could, if they chose to, "sell eyeballs" by promoting/preferring certain accounts and/or tweets over others. They could sell these preferences and promotions for twokens, which would in turn lend some legitimacy to the promotions because twokens would have to be "earned" somehow. I'm not saying this would necessarily be a raging success, only that Twitter could ground the value of twokens in their ecosystem.
