>The notion that every practicing doctor has enough free time - or is even smart enough - to keep up on the latest pharmaceuticals, is ridiculous.

That's part of the doctor's job, if they can't keep up with new medical/pharma literature then they need to find a different job. Further, most doctors know taking a ton of info from a pharma rep is just asking to be misinformed. A lot of pharma sales reps have no science background and many lie about approved populations and other aspects of a drug (just see the many, many lawsuits out there).
