Good advice for a blog or news site, but figuring out a good design becomes exponentially harder for web apps. Yes, they include plenty of text, but you also have a lot of "actions" (links, buttons, tabs, whatever). Web apps also have to balance readability with making common tasks easy. In particular, making common tasks easy may mean putting more buttons and form elements on a single screen to reduce the number of pages/clicks for a task.
