A VC: Is There A Happy Medium Between Opt-In and Opt-Out?
Mark Zuckerberg talks about this challenge in his post yesterday:
But we missed the right balance. At first we tried to make it very lightweight so people wouldn't have to touch it for it to work. The problem with our initial approach of making it an opt-out system instead of opt-in was that if someone forgot to decline to share something, Beacon still went ahead and shared it with their friends. It took us too long after people started contacting us to change the product so that users had to explicitly approve what they wanted to share.
