Now, full circle:

You see an unsupported event on your timeline on Damus (because one of your follows interacted with it replying with a note)

Now you see a note with some `alt` text that describes what that event you’re seeing is (ie, a song on #[3]​ )

And now you can click on that event on Damus and it will ask YOUR follows for which apps they know that can handle this unknown event kind.

You receive recommendations Damus open that other application (eg #[4]​ ) with the choose song selected.

Interoperability + discoverability across ALL event types.

Transparently.

Nostr IS the linked internet.

Floating links, like Xanadu Project.
