Well on technical matters people that have knowledge on the subject are more likely to tell you the right thing. It's not something like gay marriage or something. I wouldn't listen to airlied for something like ie cooking (don't know if he has any cooking skills, just use it as an example) but if it was something related to linux graphics he would probably be one of the first persons to ask.
This sounds like appeal to authority. Even if someone has knowledge on the subject, what exactly makes you think that he is more likely to tell you the right thing?
