So we have to work with what we've got.

This could be said also about the diverse community in WOX. I think the question is how we improve the engagement in the community. We need to find ways to invite more than to impose. Find the good commenters first, recognize them/value their work. This group surely will provide confidence to others to join. Recognize the work of great authors, whom provide exemplary skills/treatment of their content, provide them with good commenters to catch their attention on the interactions in the community (those supported by Art-Venture for example).

Promote voting in comments (the most difficult part). Here the blockchain rules don't help as comments produce less curation rewards (as they regularly don't reach high value $) and cannot be voted by curation trails. Many collective strategies could be implemented but need SP support. (I would study the promotion of the use of the @dustsweeper service in the community, so the users can help with those author and curation rewards in the comments).

I find some people tend to gather around nationalities and comment accordingly, maybe we can play a little with that, promoting those interactions and extending the visits to other countries. "The week of Russia", "The week of Nigeria", "The week of Venezuela", and so on... Just an idea.

Of course, we will find those users that just want to abuse, to take and don't to improve their journeys on the community or in the platform.

I think setting steps of a process will help us find the answer for the questions you've asked!
