Wow! almost all of channel9, cool though it is, is just microsoft wage slaves cheerleading about .nf**cking net, this is a genuinely smart guy giving some awesome insight into something we all take for granted but don't really think about,as someone who works with typesetting professionaly i was absolutelty awestruck by the lucidity of his corellations between animal/human behaviour and how human/animals read. Really, really impressed and, like everything when its  explained by a super smart person, seems so obvious once you comprehend. What a guy. Hope hes's been there long enough to reap the big bucks, and hes's a glasgow boy, best wishes to you man.
