Please, put some more emphazis on promoted posts, maybe share more of the rewards from promoted posts with the people who interatec with it, maybe every 10 posts on the feed or new/trending/hot show one of the promoted posts.
I am not against ads, I am against tracking the user, the promoted posts can be a neutral way to display ads, and maybe somehow, like youtube does, share a bit of the price paid from the promoted posts with the users (though the idea of burning the promoted fee is also not bad, maybe do a midterm)
Good luck either way though
