Thanks for the informative post, Tom. If people get me on the right topic, I can certainly be guilty of being "The Expert"!
One thing that I recall from team-building activites at school and university was "active listening". In essence, it was to engage with whoever was speaking in some way (for example, even just acknowledging that you've heard what they said). I think there's an equivalent in written communication as well (how many times have you sent an email with questions or in response to somebody and the reply just skips over half of what you asked/said and only seems to address what the reader thought the gist of your message was?).
