Check out !worldnews@lemmit.online. The admin of lemmit.online has set up a bot that fetches reddit posts via RSS, making it much easier to make the switch and of course not getting any ads.
You can make requests for subs to fetch at !requests@lemmit.online.
In the end we’re just using lemmy and lemmit’s bot as a simple RSS reader, so nothing illegal or even remotely unethical happening here.
It would stand to reason that if there is discussion on the original reddit thread, that it would also generate discussion here too.
Community is much smaller on this side of the fence, though.
Honestly reddit is about 100 times too big now. Most comments on major threads go unseen. It was plenty big enough 16 years ago for lots of good discussion, way better than today to be honest. Now it’s just about who can get the quickest quip in. Actual discussion is pretty lacking on reddit.
I’m not trying to say “bigger is better.” The point I’m trying to make is: if a bot starts flooding lemmy communities with myriad of links, then it will be more difficult for a smaller community to make sense of it. There will be lots of communities that has many links without comments. It will start looking like a dead village. So, it would be better if only the real interesting stuff (with high ratings) are brought in. That way, fediverse communities would have a better place to start from.
