While, of course, all employees should be able to provide feedback to management about their work environment, I do notice that both nurses and doctors are conspicuously absent from any of these reviews. So are many other key positions. I wouldn't be drawing any conclusions from this highly limited sample size.
Generally, in my experience, angry, bitter people tend to be more inspired to share their anger and bitterness publicly than happy, content people.
BUT, to reiterate, in terms of authenticity, these types of websites are questionable -- both good and bad.
