It's currently in closed beta for registrations, but you can browse and see QDOSs for many celebrities and existing users. The site is built on a semantic web platform, and you can currently get live RDF data about all the people in the system.
Disclaimer: I work for Garlik, the company that built it, and designed and developed part of the system."
