So far this sort of discoverability of communities has been hard for me too ( as someone who has been using Lemmy for <1 day). I wish there was somewhere I could go to at least get some recommendations of places to join that are semi popular and might fit my interests rather than having to go deliberately seek a specific thing out myself. It's also why I never got into Mastodon much. Wonder if such a thing exists.

Looks great! I've got a very similar setup to you but I've been lagging on actually setting up my homepage dashboard. I've tinkered with it but haven't actually take the time to figure out all the stuff I want to display on it. I might just end up copying yours! 😁
