This is a great question. I think there are three essential points:
First, we need to keep our active user base motivated. In my opinion, there's no point in looking for new people to join the network if they're just going to give up in a few months. Let anyone who's never felt like they weren't recognized cast the first stone.
Second, after taking care of our regular writer base (people who post content at least twice a week, in my opinion), we should try to increase the active user base.
Third, a complex point is the way downvotes can be used. Have you ever thought about someone downvoting you because you voted for a witness they don't like? Or because you supported a proposal they're against? Or simply because they don't like you?
Have you ever thought about "losing" 0.20 cents for each post, for example? There are people who will tell me that 0.20 more is not enough, but for us mere mortals who try to value our content little by little, it makes a difference and in the current way, this can happen
