I see two issues with that, trails and down votes.
Curation trails could edge the data mining in weird ways, for example, a new user could dodge a 10$ post because it looks less attractive than a 140$ one, and it may not mean that the 10$ one are lousy in quality in any way, The algorithm should not show content by profits, votes, or dv if we were to add.
And how would it handle dv at all? Facebook do not have a dislike, YouTube algorithm went crazy at times with the dislike, to the point of becoming a problem for youtube to work normal... So how could hive beat those issues?
Besides that i only would like to add that one way or another, is a need, hive needs to retain users, if not, we will be a high 5 with cripto, a couple good ideas that ended up being recycled by someone else later on...
