Not quite sure what to think of this one... but the Google Health product finally went live (read: beta launch)...
I'm all for centralized and open standards for information... but I'm not too entirely keen on centralized data stores of that information...
For instance, I think with putting your health stuff in Google, the amount of integration and relevant information you could attain given your records shoots through the roof! If the storage standard becomes open, then other companies will be able to utilize and talk with the service... aka instance updates, automated appointment scheduling, xfer of medical records. But, do you want Google to have yet another piece of your life? They store your wants, desires, friends, email, blog posts, and now your medical health records?
We'll see what comes out of this... I have other rants about the health industry and software that I'll bring up at another time...

I guess something has to be done about the unification of medical records. Google definitely has a gold-mine of data on us.
I haven't had a whole lot of time to digest it but they did offer a privacy statement on the sign in page ( https://www.google.com/health/html/privacy.html ).
This stuff is especially interesting to me since I work at Carol ( http://www.carol.com/ ).
@Colin - It'll be an interesting voyage I'm sure... There are Pros and Cons for Health Vault vs Google Health... but I'm sure there will be others too... Google has the whole openness of data going for them but Microsoft already has an SDK and stuff ready to go...
