Oh, and: There's no UI affordance to the editor behavior where I can click-to-unmention someone in the reply. I was certain it would break me out of the reply editor and show the person's profile instead, so when the person was actually removed from the mentions with a click, that was a surprise. Separate issue, but related to the larger "how mentions work" theme.
