I'm not sure I like the insinuations going on here, but I guess it's understandable.
I was trying to be constructive and I'm only going by mine and my friends' experiences with this. Having been on the course, I kept in touch with Kevin Burton to tell him about my progress (and to ask plenty of follow-up questions!) and he asked if I would write down some of my experiences here, which I was only too glad to do. Obviously there was no point in him posting (as the publisher), hence why he deleted his original message. But the words of my post above are my own and reflect my overall satisfaction with the MM.
I just saw the marketing site, and my only thoughts are that it's what you'd expect from such an ad - I can't tell if I'd have bought from it blindly. I quite like that they do clearly state that the MM requires you to do a lot of work. It does, but for me it's been well worth the sweat.
I hope that clears things up.
