I think it's down to the communities page more than anything else. Don't know if it's a bug with Beehaw specifically or Lemmy in general not having the feature, but you can't sort/filter the list of communities by number of subscribers or by instance.

Still a tonne better than Mastodon... My biggest complaint about Mastodon and the reason I barely use it is that if you look at all posts outside of your instance, you get riddled with bot spam. All I saw in the 'All' feed outside of my local instance were posts from a hentai reposting bot that regurgitated posts from various imageboards and anime porn subreddits...
