I think fediverse people are wildly overestimating how much 99% of Reddit users care about this. The mod team on r/futurology (I'm one of them) set up a fediverse site just over a month ago (here you go - https://futurology.today/ ) It's been modestly successful so far, but the vast majority of subscribers seem to be coming from elsewhere in the fediverse, not migrants from Reddit.
This is despite the fact we've permanently stickied a post to the top of the sub. r/futurology has over 19 million subscribers, and yet the fediverse is only attracting a tiny trickle of them. I doubt most people on Reddit even know what the word fediverse means.
When might it integrate Lemmy?
