I found Collins' first post to be very insightful, as I am no Marketing guy, nor do I intend to be. But if I was interested in diving in full time, his info would be quite useful, and I would have not trouble putting it to use.
But as a casual Saturday morning coffee sipping observer to this thread, I can't see where he was "run off" either.
I would encourage him to strap on a pair and hang around. I would bet he has much more info that could benefit us all.
