One thing I couldn't quickly tell is whether you are always remembering
the source of external information, particularly any externally acquired
personal information about someone that is stored in the database. That
may be important for business users who have to meet data
protection/personal information rights legislation. Ditto that tracker
doesn't start extracting and organising by anything like religious,
medical or ethnic data whose processing is controlled in many countries.
