Yes, there are a ton of “other stuff” clients. We have kind of crappy versions of many 🤣

Zap.stream is the best example I think of other stuff - in this case streaming!

Nostrapps.com has an OK list of things to explore.

I don’t think we have a good Substack replacement, I wish we did - nostr:npub1l2vyh47mk2p0qlsku7hg0vn29faehy9hy34ygaclpn66ukqp3afqutajft started on something like that at one point but I have no idea what happened to it. There’s highlighter.com too but I haven’t tried it in a while.

I just created openux.app which looks nothing like nostr social apps but uses relays and events under the hood.

But yeah there are hundreds of things to try!

Another one I’ll plug: Kinostr.com for movies 🍿
