A GP I spoke with recently (on Sand Hill Road, potentially even one of the firms Cringely sent his plan to) put it like this: If you aren't smart enough or dedicated enough to work all possible network connections to get referred to our firm, you probably aren't smart enough or dedicated enough for us to fund you.
This comes down to the idea that most VC's (not all), invest in people\teams, not ideas.
A submission from Cringely followed by an article on his blog definitely qualifies as a filtered referral, so any results from his 'test' wont be very representative. At least he realizes this.
