Peter, just because you don't know what Facebook is, it doesn't mean that people who use it are nerds!? You keep going on about attendance rates and how many debates he's spoken in etc but what does that mean.
I could give a presentation to Directors saying that if I do x, y and z it will save you 2 million a year; doesn't mean it is going to happen though!! And to touch on Dave's point, I know alot of people who turn up for work and have a 100% attendance... doesn't mean they've brought their brain with them though!
