I was there and I have a starkly different reaction. A lot of other people I talked to afterwards share your sentiment but I still can't shake off the slimeballey vibe he gave out. A few weeks later the Farmville scandal blew up.
I found Pincus' talk to be the worst--more so than the annual McAdoo flat-pack speech about funding.
Pincus didn't just meander, he started wandering around a Matrix simulation room and just kept opening doors and slamming them shut. His tone was also bitter, particularly about his thoughts about being "misaligned" at successfully exiting.
Worse was the video at the end. What was that? What was the point of that other than a direct recruitment video? Great entrepreneurs leverage great opportunities but to be so flagrant about it? That MTV quick-cut infomercial had no redeeming factor.
Tony Hsieh didn't speak of a nerd-nirvana perhaps, but what he did speak of was building an organization. He spoke of values and skillsets that the audience in attendance SHOULD think about and work TOWARDS. It's not of now, it's of leadership skillsets that's required in just another 5 years. Maybe less if the precocious attendees have their way.
But you did use the right word: blindingly.
