Loved this graphic for an article in The Economist titled "The Future is Another Country." The article also makes an interesting point about what makes a country:

But many web-watchers do detect country-like features in Facebook. “[It] is a device that allows people to get together and control their own destiny, much like a nation-state,” says David Post, a law professor at Temple University. If that sounds like a flattering description of Facebook’s “groups” (often rallying people with whimsical fads and aversions), then it is worth recalling a classic definition of the modern nation-state. As Benedict Anderson, a political scientist, put it, such polities are “imagined communities” in which each person feels a bond with millions of anonymous fellow-citizens. In centuries past, people looked up to kings or bishops; but in an age of mass literacy and printing in vernacular languages, so Mr Anderson argued, horizontal ties matter more.
