I take strong exception to Warnock's contention that Greylock is usually right. I think his choice of words is poor - my experience is that Greylock is rarely insightful (right?) but ALWAYS arrogant. They never have any ideas, they just follow the money. I did technical due dilligence on several occasions for one of the partners at Greylock back in the early 90s (Roger Evans) and I helped put him into several deals that helped make him millions. I have also heard him downplay and even deny that I played any role and later he wouldn't even take my phone calls (he acted like he didn't know who I was!). But these guys are not unique, it has been my experience, to a person, that VC are scum. Sometimes they are polite and well-heeled scum - but always scum.
