The influence of the Health 2.0 trend

I noticed about an interesting post on Gigaom related to the Health/medical 2.0 sector.

First, its another indication for the growing up of this sector. Gigaom is one of the popular and respectable blogs concerning the web world including web 2.0 .

Second, the post concentrated about ventures arising in Germany. Its another indication for the rising popularity concerning Health 2.0.Its not only in the states but it live and kicking all over the world.

Third, its about the ventures that was discussed in the post. They are all on the concept of rating Physicians and medical procedures.

Its interesting because its so easy today arranging algorithm observing and ranking physician but the question is if it will give added value to the patients/consumers.
Because ,how can you rate quality of medical service in ampiric numbers/values?.How can you compare between and calculate academic skills with clinical skills with reputation and years of experience (not mention many others values need to be calculated)?.
Another question is comparing between physicians on the base of prices.
The author mention the existקnce of sites which offer the consumers the ability to compare prices and make pre-shopping before theט choose the right doctor.
This can be dangerous in complicated medical service and also be dangerous because as I wrote above how can you compare only by prices alone?. There are so many quality aspects that need to be calculated.
It can cause to canabilazation of some medical sectors.

What do you think about it?
