The forum is a place of getting information with a proof and also discussion place where can be share ideas or learn a new thing with a quality post, that we attract higher rank to give merit to rank up.
I like your statement that this is a place where we get information with proof.
It doesn't really matter from whom the information is coming or who is giving the advice. Since the information or the advice would be made public everyone will be able to see it and ascertain which information is superior or useful than the other.
I will advise that you rather concentrate on the quality and content of the information or advice than the rank of the person that gave the information or advice.
Rank is how you have been while knowing is how well you know.
