What I like about nostr is the experimentation with different clients, and the fact that your identity is portable to any of them. It's just a really cool model.
I'm working on a nostr-based discussion site heavily inspired by HN/reddit: https://oddbean.com/
No login required, and you can switch to a different client any time you want. We try to keep the bitcoin/politics stuff to a minimum on the homepage. There's a lot of that on nostr, but also a lot of kind and thoughtful discussion about diverse subjects.
