The biggest surprise for me was the https://hexbear.net count, an instance I hardly interact with.

      Games is the largest games com by far in terms of posts and comments (150k comments and 15k post vs 71k comments and 3k posts on lemmy world…

      News has most posts than any other news and about as many comments as lemmyworld.

      Politics has the most posts of any politics coms, but far less comments than lemmyworld’s.

      History basically has no competitors (150k comments vs 7k for the next largest)

      Movies also has no competitors (75k comments vs 9k for the next largest).

      Videos has 56k comments vs lemmyworld’s 13k

      Music has 45k comments vs lemmyworld’s 6k

      Urbanism has 44k comments vs fuckcar’s 19k

      Granted, given Hexbear has been around for 4 years, the number of comments/posts is largely a side effect of age. But it also means calling them duplicates is probably misleading. OTOH, the main trans community there has been very active recently, dwarfing all other trans communities combined.

        They are more “community” than the ex-redditor secluded island that is most of the others instances, that’s definitely the side effect of age.

          Hexbear (if you disagree with their politics) is basically like a white american from the deep south. They’re perfectly reasonable to talk to as long as it isn’t politics
