i thought about that follower thing quite a while. I think having an overview is quite important, but i don't think it must be public.
if you look at pages like twitter or instagram, there are a lot of people taking pride in themselves to have way more followers then they actually follow. it seems to be important to some to look overly important.
I'd like to suggest/request in addition to the already requested overview, to have an >>option<< to turn the following overview into private mode only - so nobody else can see it - in order to encourage people to not care too much about that balance of follower/following. So...if it's wanted the following count can be set to either public or private. I think such an option will encourage more people to just follow whatever they like - as it is right now.
