"Zynga makes games that create no value." - I don't think that's true. They create games that I don't particularly enjoy, but some people do. And according to an earlier article, they do extract a pretty significant amount of revenue from those users.
I don't really think most startups are based around a paradigm shift either. Google = a better search engine than was available. Facebook = a better(?) social network than was available. Intel = a better semiconductor manufacturer.
I agree that there are harder problems out there that need to be solved. But most of those can't be solved by a couple of programmers in their apartments. Better music discovery and photo organization can.
I don't think denigrating success with hyperbole is a good way to make a point about what startups should be focused on.
