Currently what stands out to me is the lack of reading, nobody sees posts so nobody reads comments, and older posts are locked to comment so themes and conversations get diluted. I would say we need a natural way to incentives comments not by another reward pool, but rather by making them available to the readers, so far people can read only the title of the post and some arbitrary information, what if a substantial update was made, yeah I'm thinking comment rewards are a good thing, a few people have been offering them but those are people making good payouts. Tough question. I have a idea I'm not sure it's a good one. It will certainly not fit the Kiss strategy :D
