Here are the comments from Digg so far (a little snapshot of what the non-medical internet crowd is thinking): 

“Dubious. Log into your google acct and check it out for yourself. Uploading and sharing medical files online with 3rd party sites? Google selected doctors? Sharing all of my medical history on the interwebs..with the man?
 
Yea, I’m cool off that.”
 
“From a technological standpoint, something like this gives a huge dataset to Google to do things like look for correlated health conditions and drug interactions. But from a privacy standpoint, I can’t imagine why an individual would want to give this data to them.”
 
“Best feature is the ability to see whether or not you’re going to pull a Heath Ledger with all those meds you just got prescribed at the doctor’s office.”
 
“I wish they’d abuse my health information, do you know how much money I’d get in litigation if they did?”
 
“Google is getting scary.”
 
“Honestly though, if I was older and have a more complex health history and medication list, I would enjoy an integrated site that has all of my information. My grandparents have hypertension and diabetes type 2 and go to doctors often and they don’t speak english, so it’d be great if I can look up what medication they should be taking or when I fill in medical history charts for them at the doctor’s office.”
 
“I’m assuming the above comments are all coming from relatively healthy people that have not had to deal with keeping all of their medical information in one place. There is nothing more frustrating than waiting months for an appointment only to find that your primary care doctor did not forward all of your necessary information. If implemented correctly, this is a revolutionary system that will not only benefit individual patients, but the system as a whole.”
 
“Am I the only one who doesn’t see the point in putting your medical information online to a company like Google?”
 
“I used to be one of those paranoid users that used proxies so google wouldn’t know who I was. Slowly I became part of google, *personal homepages got me*.
Now with a service like this, I look back to the closet to dust off the ol’ foil hat.”
 
“”We will not share your health data with individuals or third parties unless you explicitly tell us to do so or except in certain limited circumstances described in our privacy policy.”
 
“We will not share your health data…except in certain limited circumstances”
well, that’s nice”
 
“Trusting Google at this point will be like trusting the Bush platform back in 2000. Don’t be so willing to trust.”
 
“doctors will just ask you guys to print out your google health information. they have no idea what paperless means. they must write everything on paper and sign it, because it proves they are responsible for your health.”
 
“1- Your most private information will be given to google.
2- They can attract billions from the doctors and medical companies.
3 - They want to control the medical industry like they control websites through their add program.
 
This service can be helpful, but in the long run i am not sure..”
