Can you imagine a world without countries? Part 2

In a previous posting, I asked if you can imagine a world without countries. Listening to Peter Sondergaard of Gartner talk, I learned that if Facebook and Twitter were countries, they would be # 3 and # 7 respectively. Reflecting on this, I was wondering to what extent it should be possible for the individual global citizen to participate - in one or more countries - in some votes / referendums online, for example using the “like” button? What’s your view?
