Bloggers threaten regimes

Individuals became publishers in 2009, using the micro-blogging site Twitter to post instant, bite-sized updates to the world. The site was founded in 2007 but grew exponentially this year.
The political ramifications of the micro-blogging trend became evident in June when Iranians used Twitter to organize and publicize protests of a disputed presidential election. The protests grabbed the world's attention. Terms related to the Iranian election made up 3 of the Top 10 news trends of the year on Twitter.
