Do we have any sublemmies designed to cater to bigger social medias? Ex findasubreddit, but on lemmy?

Ex findasubreddit, but on lemmy. So instead of posting to like r/findasubreddit, one posts to c/findasubreddit and uses that to find a subreddit.

Since, imo, esp for niche topics, the lemmyverse isn't big enough to stand on it's own. But the lemmyverse could still reduce the number of posts to say reddit.

Prob possible to use it for like other platforms, like follow for follow instagram hashtags.
