The present XKCD pokes at a major pet peeve of mine - websites that try to be "helpful" by handing out a useless mobile compatible index page to mobile browsers that request a specific article - thereby making it impossible to locate and view the specific article that was desired.

Chances are quite good that my phone can render your article even if it wasn't designed to be viewed on a phone. Please stop trying to be smart and just give me what I requested!
