So although Google's a great tool for things like "buy DVD player" it's a mistake to think it's therefore good for everything. It just doesn't have the logic to handle medical topics in any way other than "what are OTHER people saying about it?"

Specifically, Google's main tool for ranking a page is to assess how many other pages link to it, and how good *those* pages are. Wikipedia has a good diagram of how it works: http://en.wikipedia.org/wiki/Pagerank.

Maybe someday there will be a "google health search" optimized by patient wisdom, but until that day, do as this post says and go directly to good patient communities!
