Interesting that he specifically calls out their PR firm as being good. Seems that most of the advice I've seen lately goes in the other direction, eschewing a PR firm entirely in favor of more guerrilla-style marketing.<p>I think in the end, like most other things, it depends on the type of company you're trying to build. In Blekko's case they're trying to build a search engine, so they want to get as much mainstream press as possible. Someone like GitHub, for example, with a much more technical and focused user base, did just fine by going to conferences and buying developers free drinks.
