Question: can I follow microblog-y accounts via my Kbin account? And if so, how?

I see when I click the "People" tab there's a list of local users. When I'm under certain magazines, the People tab will show remote users.

I've tried searching for remote users via username on the search page (ie, my own calckey account is @johnny) and don't get any results.

Is this a supported use-case and if so, how do you do it? Thank you!
