As a long time commenter I hope your incentive for people to leave real and meaningful comments work out for all of us. In some respects it is a shame incentives have to be added for people to leave comments, but such is life on the block chain.

Engagement is the best ways for people to find each other and content to enjoy. Also comments add so much more to a post, they draw others in and draw the author out to maybe expand on a concept or a specific part of their own post. Plus they are just plain assed fun to read sometimes.
