My immediate reaction to the #10YearChallenge circulating on Facebook: Nope.
Perhaps I am a curmudgeon. In my view, the meme, which prompts people to post before-and-after photos of themselves on Facebook, Instagram, and other social media sites, is no better than a data-siphoning social engineering attempt. The viral campaign exploits our vanity, encouraging us to surrender images of ourselves from a decade ago. People just happen to be packaging the chronology of their physiognomy in a usable format for machines to parse.
