I don't usually publish links to the mass media because they tend to be sketchy in terms of accurate information and rarely contain any meaningful analysis (see my post Critical Reading) . Sometimes they mislead more than they inform.
However, yesterday's New York Times published an article titled Google and Microsoft Look to Change Health Care. Again, the article is really sketchy, but its worth reading to get a sense of where these two software behemoths may be headed with personal health records. It gives some clues as to what Google is putting into its prototype application, and some of the challenges that are likely to slow Google and Microsoft down.
Some of Google's prototype screenshots are showing up in the blog world. Check out the First Google Health Screenshots post from Google Blogoscoped.
