Technorati is a great place to find the blogs that provide you with the information that you are seeking, such as The Medical Strategist which keeps you up to date on information and summarizes the latest articles in the health and healthcare field.  Initially, you get a code such as  6BVYV43K6QAR so that technorati can identify that the post is genuine and after that, technorati follows you so that they may keep you informed.

Pretty cool, right?!
