If you didn’t know, on DuckDuckGo you can search for posts or magazines with site:kbin.social just like you would with Reddit. The same applies to any other Fediverse site like Kbin, Lemmy, Mastodon, etc… I was really frustrated because it seems like Google was intentionally suppressing them.
Since nobody has mentioned them in this thread, you should know that there are search sites for Lemmy communities.
