I think there’s room for both. Lots of people don’t care about all the API drama or about what the CEO says in interviews, and there are easily enough of those people to maintain critical mass. But I think Lemmy isn’t far off from also having critical mass in enough communities to have some staying power.

I’m now checking Lemmy before I check reddit when I want my doom-scrolling fix. But I still visit Reddit, even if less often than I used to, because it still has some unique communities that don’t have analogs anywhere else. For example, there is no fediverse equivalent of /r/AskHistorians (that I’m aware of).
