Following this "small data" concept I was also working on an app that works with a kind of "binary communication". You guys (and girls) seem quite critical, so I'd be really curious to hear what you guys think of this concept (sorry if this is considered self promotion, it just seemed appropriate to mention it here.) The idea is a messaging app where recipients can only reply Yes or No, and is intended for quick questions when you don't need an excuse (i.e. "Have you sent the file yet?"), the idea is to gear for wearables and provide a swappable tinder like interface for quick questions. http://www.getmoshimoshi.com
