I'm not just talking about popularity. To be frank, communities moving to discord is a problem imo. Discoverability is, frankly, garbage. Information provided by others users cannot easily be found at a later date, and even then YOU DONT KNOW where the information you might want could be. If I want information on an old game for instance, on a reddit or Lemmy like platform searching for the game would yield a result, on discord I'd first have to find out which communities exist and then search each one separately, filter out the garbage (Discord conversation is a lot harder to parse and a lot less information dense than Lemmy or reddit)... This leads to having to ask again, old information might be lost and much time is wasted, both for the person asking the question and the ones answering, for no benefit. Hope you can see my perspective here
