I have got answers that it is possible to build other applications than Twitter/Telegram like. I used to develop but I have moved too far from that so I have lost the detailed technical knowledge so I can't figure out this for myself. What I don't understand is how to build other applications. Maybe dumb questions but in the different Nostr clients I use now there are basically the same fields and same functionality. How do I add another field that I want to use in current implementations (social media) or totally different fields which would enable another kind of client application? Or is Nostr locked to social media with a fixed set of fields?
