You took a single line from what I said and completely misconstrued what I and my team [used to] do, making a wide variety of incorrect assumptions along the way.

There were a half dozen of us at working for dozens of clients for a few years. Some targeted mommy bloggers, others bigger tech publications, and of course we have great relationships with many major journalists. But when we didn't, we would email. And our hit rate wasn't incredible, but saying that the other emails were worthless is simply not true. Those emails resulted in millions of dollars of sales.

If "PR" means "getting a write-up in the New York Times" then sure, most small companies shouldn't worry about it. But for most of the companies we work with more write-ups in smaller blogs and the occasional TechCrunch writeup means more sales; it was a direct, causal relationship that worked (and works) wonders.
