One of the harder aspects of navigation in lemmy is seeing interesting new communities on remote instances. What if there was a post here (meta) or chat that had links to all the local communities and when a new post is made to yiffit, a comment is added that links to the chat/meta post. That way if someone stumbles on something here they like, they don’t have to use some work around to see what else is here. I don’t know much about the lemmy API, but the list could simply check once a day?/week?/month? and update the post if anything changed.

Yes, I am aware !newcommunities@yiffit.net exists, but remote users probably aren’t. I am also aware of the link in the sidebar (when present), but that is outdated and you only see it if you know its there.
