Question for #fediverse experts (maybe npub1xzmt2d95f7watzyqktl982d7jfe5ptktusv4j20csz8nxxgmhq6q30eykm (npub1xzm…eykm) himself?): do we know how many Mastodon users have opted into search indexing across the entire network? I'm writing a post about the open web over 2023, including a section about Mastodon's improvements this year — so I'm curious about the search detail, if it's public yet.
