It sounds like a lot of your issues come from either clients doing a bad job of implementing them, or not aligning with the way you personally want to use Nostr.
I find the experience much better using Amethyst. I get notified about quote posts, and zap splits are a great feature that does work. It's disappointing other clients drop the ball so hard on this. Amy even goes a step further and let's you fork a note, taking the original content and being able to repost it as my own, with edits if wanted, with a link back to the original authors note.
Ownership of content is an interesting thing to take into consideration. I often see my memes posted by others, accumulating zaps that don't go to me, and commentary I don't get notified of. It could be annoying, but I choose not to care. I put it out into the world, and the world will do whatever with it. Maybe Nostr needs to integrate licensing and DRM into notes to stop that from happening. People could mark their notes as proprietary, or open source depending on how they feel.
What is your opinion on highlights that Gigi has been playing with so much?
