We Know What You’re Doing: Website Exposes Facebook Stupidity. A new website "experiment," WeKnowWhatYoureDoing.com, seeks to teach people why Facebook privacy settings matter. For all the uproar you hear in the tech press about online privacy, it’s remarkable how many people violate their own privacies on a regular basis. And now a new website called “We Know What You’re Doing” seeks to expose just how foolish many people are about what they post publicly on the Web. A brief look at We Know What You’re Doing (aka WKWYD), which was launched by 18-year-old British Web designer Callum Haywood, shows just how many absurd, ridiculous, and downright idiotic things people say — publicly — on Facebook.
