100%. Sports is a biggie. I run a college hoops message board for my alma mater and most news and information breaks there.
Maybe one day nostr will have a proper full feature forum client 🤞
The optional Reddit-like Nostr features are, in my view, an important goal. Reddit used to be a free speech platform. It grew that way. Many complain about Reddit moderation and have complained about it becoming more censorship prone. So there is a potential userbase for a Reddit-like Nostr-based platform.
