As you use it I think it will make more sense and the possibilities require money to be apart of the mix. Decentralized money is needed for a decentralized internet. Very few altcoin projects are truly decentralized money and most of them don't have much going on.
It kinda also ties into the Value 4 Value (https://value4value.info/) system (Nostr/Podcasting 2.0/Etc.). If you find value from something, you can send some value to get more of what you like.
Just a small sample of projects going on with Nostr integration that are not twitter clone/social focused (although all sorta leads back to social through sharing):
Market: https://plebeian.market
Nostr Streaming: https://zap.streaming
Recipes: https://nostr.cooking
Data Storage: https://nostr.build
Games: https://www.thndr.games
Anyway, I'll stop bothering you on this topic. Haha. Have a good night. 😃
