it is a good reason, bu it think some people want to know if they have more or less follower to communicate with their community. Some other notes talk about a way to make influencer come here from other social media, this is an important data for them. This number don't have to be exact, it should be a "rounded" one like ~100 ~1k ~1M and not an exact number. It would respect the fact that decentralized network don't have this exact value, but also the need to know "how many follower i can communicate with" for the ones that care about that. #nostrIdea
