I’ve noticed that lemmy is full of discussions about Twitter and Reddit, so that’s probably the reason these kind of posts show up, but with niche topics it’s a lot harder to find something. I’ve tried searching, even with the lemmy search engine, a post I made on c/Android using generic words, but I couldn’t find anything at all.
I just found a post on the Fediverse community, it shows a new search engine designed to replace google’s “site:reddit.com” search query. Hope it will work.
Unfortunatly tons of data are still on reddit and I think it will be hard to recover them. There are some people who scrapped terabytes of posts and comments from Reddit so I hope they will be of some use in the future. Anyways, I should try finding more niche communities and engage with them
