The blue check on your account doesn't tell me what about the account has been verified. It probably means you're the Steve Klabnik that shows up a bunch of places in a web search, but that would mean much less if someone else also had that name and a web presence.

Your verified domain name tells me much more, but I recognize that's not the right verification approach for everyone. What I think would be more meaningful is labels like "@rust-lang.org says @steveklabnik.com is a Rust core developer" or perhaps a label with some metadata given special treatment in the UI showing mutual affiliation, e.g. "@rust-lang.org and @steveklabnik.com say they're affiliated with each other".

Edit - a further refinement: instead of verificatiions, allow accounts to feature labels placed on them by others for special treatment in the UI.
