No, I think its a good foil. Some of the advice on here is down right questionable ,and sometimes potentially dangerous. So frankly, I like to see a little opposition every once in a while. Besides, I don't think these guys are coming in there to "debunk" so much as they are here to help as well. They just do it from a different paradigm. Shoot, half of them aren't even doctors, they are just folks who are into logic, reasoning, sciences, etc...
And its not like anyone is prescribing anything - I think the most consistant advice is "you better get that checked out by someone who can actually see it"
Besides, its not as if this is a members only club.
I wish it were called "Yahoo Opinions" because I wonder then if people would be so ego-involved in defending a position? I think somehow that name "Yahoo Answers" - implies there is a right and wrong - and in some cases, there isn't one...so why do folks get all wound up about it?
Eh, just my two cents.
