Ivan -
I think Dave already explained himself really well. But what I have noticed about Dave is that he thinks founders don't push the boundary enough and take enough chances to market their company. Case in point I was giving Dave ride one night (long story) and he was exchanging emails with a founder of a newly funded company. I was able to guess the company, and what I gather from Dave was that the founder/CEO was being a bit cautious against his recommendation. I think Dave's post is very much inline with his philosophy and his brand. Perhaps this is his way of winnowing the hustlers. Basically, if you dig his approach then perhaps you share a bit of DNA with him.
