It's unfortunatly all over the place. quote post is critical in my view. gossip handles best, but can be confusing if coming from a different client

💯 they are essential.. Quote Postes provide context and for readers it’s a better discovery of new people to follow when you are adding comments as it’s like an endorsement to go read it
Gossip currently interprets incoming quote posts pretty well I think. But it is not generating them properly when you compose a quote post yourself, it still doesn't support NIP-27 in that regard and puts '# [ 0 ]' kind of things in the content instead of 'nostr : nevent' links. This is in the process of being reworked.
nostr:#[1]
I've made changes to nostr-types to define NostrBech32 and NostrUrl with to/from string functionality, extracting from notes, handling of all nostr URLs, and handling of the 'nostr:' prefix. But I just pushed it and gossip isn't using it yet. There is still a tricky bit about when to include an 'e' tag and when not to.
