That was incredibly interesting! The blog is mine, by the way. I'm incredibly flattered that you made such an in depth analysis; frankly I wrote it as nothing more than a happy rant and wanted to share with some fellow hackers and entrepreneurs.
I agree with the sentiment that the Myth of the Valley is interesting and frustrating. Mainly though, I think it gives many smart people a strong sense of purpose (not unlike the prophets and religion in general), and I definitely think that's a good thing.
