Essentially all of the ones that I used. r/Minecraft, r/minecraftsuggestions, r/conlangs, r/vexillology, r/pixelart, etc.

The thing is that all of these have communities and magazines on the fediverse — it’s just that there’s little, if any, activity on them. I don’t think you can really say that these communities are here if they have one person posting on them regularly.

The only communities that actually have a solid amount of activity here are ones about memes and news. If that’s all that you used Reddit for, then the fediverse is doing great, and such people will act baffled at how anyone could stay on or miss Reddit. But for everyone else, the content just isn’t there.
