One thing I learned at the Q&A was that Brian's screen-name is going to be obsolete next year.
One thing I have since learned about the Q&A, almost one year on, looking through the list of questions that Brian did get round to answering, is not to expect the earth (as I did at the time, with a misplaced outrage at questions he didn't answer) but to be thankful for what you do get. And boy, it was more than anyone could ever have expected only a short while before. Thank you, Brian, thank you, mods.
