What do you mean by "startup"? The one I normally use is Steve Blank's, "an organization in search of a repeatable business model".
If that's what you're talking about, then a lot of this advice still applies. Looking at the "Pocket Guide" section, for example, I think that all still applies for a niche startup.
If, on the other hand, you're just talking about a new company, one where you're applying a well-understood business model to, say, a new location, then yes, you need different advice. But I think that advice differs a lot based on what kind of new business. The advice for a first-time Subway franchisee should be pretty different than somebody who wants to launch their own consulting company. There, it seems like people form up into specific communities around the kind of business.
