To the surprise of no one, Facebook has announced that it will no longer forward your facebook.com emails to your actual email, thereby giving you yet another reason to open up that app or visit their page so they may collect that sweet sweet data about you and sell it to advertisers.
In Russia there's the fantastically creepy and unavoidable app called Findface, where you can upload an image and find that person in other images on open social networks. It was only a matter of time for someone to start using this to make a point.
I keep telling people who work in advertising to "get out of advertising", to find their inspiration elsewhere. Talk to real people, enjoy art in galleries, spend time with retirees, go to soccer games - in short, be where the target market actually is, in the real world.
