While I have much sympathy for Rich (way more than for Clojure), I find his talks to be extremely simple. He can talk hours about very basic and obvious things. Overall, at the end, I'm not getting much new from it.
What he talks about may be obvious to you, but is probably not the reality for 90% of the industry.
All the smartest people I know (far smarter than me) are constantly impressed by his talks - and discussing with them often makes me realise I've missed some bigger-picture concepts.
So my conclusion (in lieu of a chat over a beer with the person to dig deeper) is to assume that superficial dismissal of his talks mostly demonstrate a superficial understanding of the content.
