If I ever get blocked, banned, deplatformed, whatever—people would see my domain and be able to go there to determine what's going on. In a sense it's "censorship-evident".
I think this will be great for businesses—it's so much more less ambiguous if I can @example.com a business and get a response. I put a starter pack together of SaaS built on Rails that's already doing this at https://go.bsky.app/JQyXa2u
I really like what BlueSky is doing and hope it doesn't get enshitified as the future plays out. Even if it does, it seems like now is a goldilocks moment where things are feeling really good there.
I highly recommend spending the 5 minutes it takes to setup an account and point it at your domain.
