Is the internet and Yahoo! Answers such a good place to come for answers?

Using the internet is great; I use it myself everyday and often come on Yahoo! Answers to find answers to my questions. However, something that has been bugging me recently is the wealth of answers and knowledge submitted by normal everyday folks. When I see questions asked on (let's just say) skincare, one person will recommend this, but another person will say that same recommendation would not work in a million years. This same trend seems apparent all over the internet so it can be quite hard to obtain an objective answer. Do I take person A or person B? Do I spend more time trying out both answers or do I go and seek professional advice? Doesn't this become confusing with so much choice of answers. So my main question is: is the internet too much of a wealth of information?
Thank you. And I not grumbling, promise! I'd just like to know, (somewhat ironically given the question) what you all think!

True, but have you been to more than one doctor lately? Even asking "professionals" you get the same contrasting answers.
