I think the nostr communities should be abandoned altogether so clients won't focusing on it until a better proposal shows up. NIP72 was a "nice" effort and failed super quick. Not only it doesn't work but goes against the very idea of nostr.

The way communities are implemented now dose have a lot of flaws. and the way NIP-72 is written leaves a lot of features out. but I don't think communities should be abandoned.
While there are many ways for people to organize content ( hashtags, labels, lists ) I think there is a need for a reddit-style feature in nostr. basically a single page of content that is moderated by multiple people
I guess the moderation aspect of it is opposed to the free-speech core of nostr but I don't think its incompatible
As for communities in noStrudel, I've got a few goals
1. Change community posts to a non-kind 1 event so they no longer show up in users timelines
While this will definitively hurt communities and make even less users see the posts. This is probably necessary to build the next thing
2. Build a central "Latest", "Controversial", and "Top" view that shows popular posts across all communities
I think this would really help people discover new communities and make more community posts
3. Integrate zaps more to incentivize moderators and posts
I haven't really thought this thought yet 😞
I haven't spent too much time on reddit but there anyone can freely post (with enough karma and shit) and the mods can later take it down. However as I understand once a nostr event is signed there is no going back. Relays and clients can decide to delete or ignore but the signature can't be withdrawn. (Please correct me if I'm wrong.) If this is the case then there's this fundamental difference which prevents nostr function like reddit does. Not to mention the trolls who like to abuse NIP-72 rn.
Also as nostr:npub1qfkcklnmes45z75y7y8dkud5yll8vp5eq5ysk9rmgqdxeasv8unsrfj6kq mentioned elsewhere a community post that is not approved can be seen anyway under Pending and in Global too, basically the approval stamp is just a gimmick so what's the point in the first place? (Don't get me wrong I'm not arguing with you just thinking out loud.)
Can't be communities made like bots? It would repost notes that match certain criteria similar to your second point and anyone could (un)follow, mention and zap it.
