I think there could be a service like this, but that relied on the already standardized types of data and categories such as schema.org. The service could work like a hub, parsing private addresses people where indie-people would host their own preferences (for example, their own websites) and giving this data to external services; and, for common people, the website would host the data for them, also in a microformatted way (so other hubs and parsers could grab data from it).
