Exclusive Social Networks....good idea?

Recently I have seen several blogs on exclusive physician-only social networks. Sites such as Sermo and Ozmosis adn Tyromed have popped up creating a place for physicians to share ideas and collaborate. My question is, is this a good idea?

Do exclusive sites like this serve to generate new knowledge, new ideas, and new innovation....OR do they silo thoughts into the doctor world, lost forever? I cannot honestly answer that because I am not a physician and cannot access the sites... SO am I feeling left out... Not likely. I do wonder about the effect of theses sites though. Do they continue to widen the gap between docs and other specialties like nursing, respiratory, administration, nurse practitioners, and PA's?

Wouldn't sharing case studies and collaborating with the health care team only serve to create better outcomes?

I understand the need to create a site that the general public cannot access.... Although patients do have a say in the world of health care, an open site like that only serves to breed another MySpace. But a collaborative website that includes all health care workers and promotes a professional exchange of ideas and collaboration seems like a better idea.

Keep your eyes open, as a site like this will be beta testing soon!!!! I will update more as this occurs!!!
