Follow those who will make your feed interesting.
I know Jack about customizing cars, ants, or BTS but I follow those who post about them to get new perspectives.
I do know a lot about moss though, so similar ideas is one reason I follow, but that's about a hashtag. ( #mosstodon )
Got lost somewhere in this question.
Are you trying to get more follows? I say forget that and try to get more emotional benefit from the feed. #follow
