Not sure I see the applications of this, but I guess more high-level error messaging is something that is in general a good thing so I guess that should hold for the web, too.
Application will be www.google.com, www.youtube.com, etc. They'll get censorship instruction from gov bodies. There are two things that are obvious now, fight google vs facebook is like who will be big brothers right hand and other is that RMS was right. Sad thing is that it is first time in human history that evil oligarchy can be beaten by engineers (google, facebook, ...). Too bad they don't get it :-(
