On the topic of "discoverability" and taking the nostr and the X as example...

Google content indexing works much better for centralised platforms than it does for a decentralised network. I can pretty much go to Google, enter a phrase I remember from a persons tweet on X and I will find that tweet right away.

Now try the same for a note. nostr content isn't being indexed like traditional content which makes perfect sense but at the same time works against discoverability and SEO.
