I am reassured on a regular basis by learning analytics advocates that people don't mind sending all their information to online services. But I think that the evidence speaks against that. For example, "the newest data increasingly support the idea that young people are actually transitioning out of using what we might term broadcast social media—like Facebook and Twitter—and switching instead to using narrowcast tools—like Messenger or Snapchat." Sure, these companies might still be aggregating private data, but the intentions of these users is clear - to keep their goofy messages and candid snapshots private. And the implications are significant. As the article says, "if young people are no longer “liking” things on Facebook, the platform’s long-term value to advertisers may erode." As well, parents will be less able to monitor them, and they will be less exposed to trends in social and political discourse.
