Social media can be a powerful tool, especially when considering how it empowers regular people with the ability to reach a large audience. It certainly played a prominent role in the Arab Spring protests of 2010, when protestors took to Twitter and Facebook to document the uncensored reality of their experience.

When the pundits talk about Vladimir Putin’s offensive in Ukraine, they usually mean troops and tanks, but his greatest weapons are ,in fact, his propaganda machine and the gullible western media. So far, he has been winning stunning victories without firing a shot.

Sustained anti-government rallies in Thailand, Ukraine and Venezuela have captured the attention of millions. But large pro-democracy demonstrations in Burkina Faso last month largely escaped the Western media’s radar. Since January, tensions have flared between the West African country’s authoritarian government and the impoverished masses yearning for democratic reforms. Depending on how developments unfold, the protests in Burkina Faso could serve as a catalyst for further uprisings in the region.

In 2012, after having been sentenced to 11 years in prison for "terrorism" for illegally entering Ethiopia from Somalia in the presence of the Ogaden National Liberation Front, Swedish journalists Johan Persson and Martin Schibbye took the advice of their legal council, confessed to their "crimes" and requested an official pardon. It was a pragmatic move - both journalists vehemently denied the charges and considered any confession to be a charade - taken to save their own skins.
