I understand that lemmy is a great place to be in for discussing our experiences with Android phones, but l find the forums/communities great for discussion purposes. The signup is very simple, just with an email id. Whereas in lemmy, an instance can have several communities, a community based on discourse would be exclusive for that purpose.
OK, but you know those are extremely simple. Not any thing like a social medias algorithm.
But ok, I will concede that something popular could be at the top of a list.
