Search engine indexing (or the lack of it) also works against discoverability for users but also for nostr itself. Let's take X as an example. If I can't find a tweet but remember the author and some of the content of the tweet, odds are I'll find the tweet immediately through Google. For nostr this obviously doesn't apply and literally kills SEO and discoverability on a different level than just user discoverability.
How can we solve this? I don't know. Just throwing it out there.
