"I do think there are some use cases to be made with healthcare and geolocation services. But I also think that there's a broader opportunity for taking some inspiration from geo-location services like Foursquare. Geolocation represents only one form of Metadata - and I think it's possible we could build "check-in" services for other kinds of metadata related to healthcare (or incorporate them into existing and widely used services). So imagine "checking into" a disease state into a service which provides networking and other services for patients. ...It's something to think about: right now, I think since we're in a transitional phase as these media proliferate and grow and evolve, it remains to be seen how healthcare social media shape up.
