Remove Secret. Account Completely

 

 This might be the best social media app most people haven’t tried. The premise is simple: join into a group of friends (or create your own), and then share an anonymous message. It’s great for fun interactions, idea starters, or just finally getting something off your chest. (Editor's note, 5/13/2015: Secret has folded. Co-founder David Byttow writes: "After a lot of thought and consultation with our board, I’ve decided to shut down Secret. Over time, I plan to publish postmortems so that others can learn from the unique mistakes and challenges we faced and the wisdom gained from such an incredible 16 months.")
