This is a prototype. The goal is to design a site that encourages people to answer questions about themselves (personality, lifestyle, health, etc).
The big picture idea is to build something where people find it fun/rewarding to share data - because they get interesting results, and/or because they understand this can help others. If we collect enough data from enough people, we can leverage machine learning (deep learning / AI) to tell people things that help them better their lives.
