I would create tokens called Comments (CMTS). Users would earn them from making comments on the steem blockchain. Users could earn or keep their tokens for upvotes. There is a base upvote amount that is subject to increase depending on the quality of the comment. The amount of tokens you earn from commenting daily, is limited by the number of tokens you hold. Signup would be similar to steemconnect extension. Once you log in through it, start commenting.
