Don't forget the problem from the other side, too: how to detect and bridge inferential distence for knowledge-havers, i.e., how to find the knowledge-gap and convey the information to them. (That was actually the long-delayed article I'm working on, given my success in teaching others and my difficulty in getting others to convey knowledge to me when the roles are reversed.)

EDIT: Nevermind, I didn't read the discussion before saying that.

(The use of the term "knowledge haver" rather than "teacher" was deliberate.)
