Fediverse users are sceptical, so for now threads uses can only find users who willingly intact with people on threads. They're taking a carefcareful approach.
I assume if threads users follow fediverse users the content makes its way to their feed as normal.
Strong agree. Mastodon already works so that your feed won't be filled up with shit you don't want to see.
On a personal level, I couldn't care less.
On a professional level, I want people to be able to follow me no matter which idiotic service they are using. So I'm bridging to Bluesky and I would be happy with my content being spread on Threads as well, though it doesn't seem to attract many academic users. I have no idea who that platform is for. But if they're interested in seeing my boring academic self-promotion, that's cool with me.
