Thesis: a web of trust based social network wouldn't have a reliable "global" follower / like / etc count -- it would only be the ones you've seen -- and this would be a feature.
Some of the most toxic behavior on Twitter comes from people trying to become "the most popular person in the room", which also leads to a lot of social messaging which isn't about being constructive, but differentiating yourself in a way that makes you look better than others.
By having a public follower count, *everyone* (yes, even you, yes even me) is gamed into comparing whether your follower count is higher than others, whether others got more likes / shares / etc than you.
This isn't a good basis for thoughtful communication.
BTW some of my recent thinking on this was prompted by @nolan's recent blogpost https://nolanlawson.com/2017/11/15/why-im-deleting-my-twitter-account/
