Yeah, I think there's a narrower focus than what might have been originally implied. I'll let John come in tomorrow and clarify, but most of what John and I deal with are either Web startups or tech sector directly related to web (cloud, hardware, consulting, analysis firms, social media and design firms, iPhone design firms, Facebook development houses, ad agencies that monetize one or more of the aforementioned company types).

This is our world, and though the Silicon Valley startup world encompasses more than these types of companies, this is what was likely in his mind when he wrote it (and the context by which I interpreted the post).
