But there IS a distinction between web site and web app. Blogs, news, forums and the like should not be web apps, they shouldn't use client side rendering and fancy widgets. The Spotify web player however IS a web app, and it would suck tremendously if it wasn't built as such. Can we stop with the black and white reasoning already? Yes, many things that claim to be web apps today shouldn't be, but that doesn't mean there aren't legitimate uses for it them.
