Apple this week pulled a Facebook app from the App Store. It’s called Facebook Research, and its purpose was to let Facebook watch everything that users did on the phone. Apple says the snooping app is too invasive, even if users had consented to letting Facebook watch their every move.   Which raises the question: How much social media is too much? Are we giving these platforms too much data? Are we posting stuff too quickly without thinking about it? Is it time to step back?  With me this week, Farhad Manjoo, a New York Times columnist who recently wrote a column about the response to the controversy around Covington Catholic students, and how that inspired him to change his Twitter behavior.   Also with me, Jeff Jarvis, professor at the City University of New York and longtime journalism commentator. Chris Moody is a former data strategy VP at Twitter, currently a partner at investment firm Foundry Group. And later, Jaron Lanier, noted computer scientist, and researcher at Microsoft.
