I've added some good blogs and website resources over on the sidebar. If you look under "resources" you'll find a number of new links.
I've been impressed with the content of all of them but if I could single out a couple that are simply first rate on content, take a look at Robin Fisk's comments about managed care contracting as well as Roy Harmon's comments about health plan law. Not to mention the two law professors' blogs and CCA Strategies. Check them out yourself; you could spend a lot of productive time keeping up with these folks.
