Title is a bit of a loaded question but I tried to fit it into one sentence.
Do you think Lemmy’s search and use functions are hurt by all the communities that were made and abandoned during the 2023 Redditfugee influx? As in, do you think that Lemmy would be better off if some of these communities were consolidated into larger general pages until it gets a big enough user base to warrant individual communities for specific TV shows, for example.
I don’t think it matters. Communities can specialize in whatever they like and as long as they belong to a large enough instance they should get some level of traction.
There are numerous reasons people might want to split off. For example if an anime community is being dominated by news and release dates maybe fans of a specific show want to go somewhere they can talk in detail and they can find slightly older (ex. 2 months) posts to engage with.
People who want to seek out a specific community can.
