In the current THES is a comment article on the use of social media in politics - this seems to happen mainly in non-Western countries, for whatever reasons. Maybe lack of trust in traditional broadcasting media? Would Twitter be more relevant in the UK if the BBC didn't exist? Or are people using Twitter but it is just not reported as journalists don't notice it? With the more limited and controlled flow of information coming out of other countries one has to look out for alternative sources.
And the interesting bit is at the end of the article: a call by a professor from Delhi to study social media in university seminars, rather than just films and literature. Good to know we're early adopters in HtB!
