Good point, plus doesn't the study end in 2009? "Budget Cuts and Social Unrest in Europe, 1919-2009" It just addresses growing media penetration? How on earth

Good point, plus doesn't the study end in 2009? "Budget Cuts and Social Unrest in Europe, 1919-2009" It just addresses growing media penetration? How on earth can this study address social media with a data set that is mostly pre-2000? I think the best we can say now is that the jury is still out. I have no idea how citing a study where the bulk of the data is from the 20th century can say anything useful about social media. Thanks for posting the link to the study though - always glad to see folks trying to back up their assertions with evidence.
