I checked my profile on the two sites in the Med Economics article. On vitals.com I got good reviews, had a couple of "recognition" awards I never heard of, and found out I was the team physician for the Tallahassee Tiger Sharks (200 miles from my office) and was on the surgical review committee on a Tallahassee hospital (I am an internist). On RateMds.com there were no errors, but no ratings either, and the site offered a link to my "online appointment site", which was interesting since I don't have one.
So I don't know that there is much useful on these sites, at least not for me.
