Quora have blocked Quora from being displayed in a frame, so QuoraAnonymous.com doesn't work anymore. :(
It was basically just a created as a joke and a tribute to Quora, although personally I did find it helped me get some work done, remember to eat, and eventually force myself to call it a night and go to bed!
I don't think the action was taken specifically to prevent QuoraAnonymous.com, but I don't think they are likely to accomodate a third party displaying their site in a frame, now they have taken action to block it. This site only ever displayed nags at the top of the browser, telling you how long you were logged in, and to get some sleep etc., but it would have been trivial to display adverts, or piggy back some other activity that Quora would have no control over.
