I'd be mildly interested to see a list of these failed democracies. My other question is, did they fail because Twitter allowed unfettered tweeting of all kinds of unsavory thoughts and ideas? Or are they places where most people don't know what Twitter is?

Edit: It also begs the question of whether democracy is the best form of government for every country, but I leave that aside, since I'm not sure we've reached agreement on whether Twitter is really that important or influential in the lives of governments and societies.
