Going to a conference and then publicly ripping the participants (while being or not being a hypocrite about it) is just about as trendy as starting a startup. I bet there will be 199 more posts strewn about HN just like this by the time the conference is done.

Edit: I want to add that everyone loves to repeat all the smart things they read on other blogs on their own blogs in some vain attempt to seem wise but how many people actually get it or even follow their own advice? Saying something isn't the same as doing it.
