Sounds like very useful technology, and it must be doable if similar tokens already exist on BitShares. Now I should think back to when I was interested in other other topics than cryptocurrencies, in order to apply it as a reward for posting on or moderating a forum, for instance.

I just hope this won't bring too much greed to the community. By the way, yesterday I saw a plan for meme markets on Ethereum, which seems much more complicated than tokens on Steem.
