What links Ashton Kutcher, Anthony Weiner and Woody Harrelson with Kenneth Cole and Nestle?

Collectively, they’ve made some of the biggest blunders in the history of social media. And they’re not alone – it seems like every month a new brand or celebrity will firmly place their social foot in their (rapidly-widening) mouth after doing something so stupid, and so wide-of-the-mark, that all we can say is… what in blue blazes were you thinking?

Some of these incidents were ill-advised but fairly forgettable, such as Woody Harrelson’s Rampart movie snafu on Reddit, and, egg on face aside, no real damage was done. Others, like Kenneth Cole’s attempt to make light of the uprising in Egypt by jumping on the #Cairo hashtag, and the infamous Anthony #Weinergate, were disastrous.
