@ewb As far as I remember, many of the early Mastodon users were actually quite averse of discoverability. There were a lot of experiences of abuse powered by attackers being able to easily delve into the past, or dig up connections, or pile on targets as a group.
Not all of the design decisions in Mastodon were useful in that regard, but there was a lot of discussion on search and quoting in particular.
(Maybe there should be some kind of history project on that...)
It's just Ethan.
