The only thing that'd be cool is if these community browsers could add the search for other communities as well, like for the kbin aggregator's communities. There's one called RedditMigration (https://kbin.social/m/RedditMigration or @RedditMigration) that has more than 250 posts, and it's started on kbin.social. It would be cool to be able to search more easily other communities so that it's easier to find the content on the fediverse.
Kbin can improve its community search too but I am finding it easier to know about other communities not on kbin on its search. Whereas, on lemmy, maybe it's because I'm on a lower population instance, but it's very hard to find a community if it's not on lemmy, and I didn't already just know about it from the kbin account
