I am developing a website for electronic personal health records. It is seen that there are plenty of websites offering PHR and almost all are free. Even then it is not at all popular.
Hence I would like to know:
1. What are the reasons for its un-popularity?
2. what shall be done to overcome it?
3. If it is made as per your requirement will you use it? If not, why?
4. How much subscription yearly be suitable?
