Secret, the anonymous-sharing app that took Silicon Valley by storm early last year, recently underwent a serious overhaul that saw a massive app redesign, a new private chat feature and a renewed focus on location-specific missives. So, for example, instead of confiding your innermost desires to your "friends" (which are essentially people in your contacts list), you could post them to a location, which should theoretically hide your real identity even further. Over the weekend, however, Secret introduced yet another new feature: You can now post to specific events as well. The first event Secret is trying this out with? CES 2015, of course.
