Getting back to the briefing for a minute, I guess it was OK. The problem, of course, is that I didn't have the benefit of hearing the actual presentation like Steve Metz did, so my take on the slides is very different without the context added by seeing the actual briefing. I'm enough of a powerpoint ranger to know that the slides are probably less than 50% of the content, if that (at least that's been my experience). Hence I'm inherently dubious about taking PPT presentations at face value unless there is detailed information or the text of the briefing is on the notes pages - something that is all too rare. To be honest, I really wish people wouldn't release slide presentations without the other content included in some form. Tufte's pamphlet/book on powerpoint ably demonstrates the dangers.
