Tuxguy, thanks a bunch for the comment. Yeah CureTogether and PatientsLikeMe exist, but they didn't seem to fill the specific vision for a complete product I had -- which was THE location for people with a specific chronic condition to go. In order to do that, you kind of have to make a place more than a product. And my hypothesis is that making a place for this purpose requires the perfect balance of social elements, health tracking, and knowledge sharing (q&a). I can dig into it more, but the basic essence that as hard as some of the other players have tried, they still have yet to capture any Facebook-esque stickiness to their services. I believe that there is room for health software that does have this property. That patients really identify with, and will come back and use.
