An innocuous and untalented video clip gets posted on a web site. Someone likes it and puts it on YouTube and before long several thousand people have seen it and passed the clip on via Facebook and Twitter to thousands more. In a matter of hours the clip has gone viral and out of control whilst the person who made it is still blissfully unaware of their new-found stardom. This is the scenario presented by Tom Scott in this TEDx talk.
The scenario he describes is not true (yet) but it's made up from several true stories and shows the potentially frightening power of today's social media. Certainly makes you think about taking control of your digital identity before it's too late.
