yeah, but who would think you are “better” just because you have lot of followers and fallow only a few? 
Even it’s true I noticed that especially the big authors who have really a lot of followers do fallow only a few - but its more on insta where it is understandable because you see the content of all you fallow so fallow thousands of your readers would end up in missing a lot of content of the people you are really interested in following.
But on the app which the fallowers have no function at all (sadly) so here it must be simply about collecting them like somebody does collect cards.
