We're all sad to see the Olympics fade into the mists of Bob Costas-narrated memory, but more than individual people, it is the nations themselves that are sad to see the Games end. For once, we were not the hyper-individualized stars of the Internet we have all convinced ourselves we are - we were part of a much larger Facebook group: our country. Here we've "favorited" (get it?) some of the best tweets from those nation-states that made the 2012 Olympics so special.
