This article is really short sighted, wrong and biased. Some users might just use your app from the browser, in that case URLs do make sense. You don't need to have a URL for everything, you should just have URLs for things you would want your user to bookmark(which can be nothing, depending on the project). For example I really like the fact that every GMail message I have has a unique link, which I can refer to from documents and other places. But let's say your app will only be accessible from a webview for some reason, you still get benefits of having URLs: you can record them and have a rough overview of what a user did in your app and you can safely issue a refresh command in your webview.
