We could build a lot of cool stuff if people used RSS. You can host stuff on Nostr and stick it in a RSS feed.
nostr:npub196qvw7utjs0cnztlg4aww98ekql9svm6c4wlv6sug70nzz0uujxsprafme is a perfect example of this.
nostr:npub1tn2lspfvv7g7fpulpexmjy6xt4c36h6lurq2hxgyn3sxf3drjk3qrchmc3 is a great use for this.
