I disagree as well. Certainly most code that runs when you actually view a page in a web app is O(N), but there are many web apps that do backend computing that is much more complicated. Take Google and Netflix as examples.

You'd better believe that Google and Netflix have scientists who work hard every day trying to "bend the curve" towards O(N) in all of those applications.
