Firstly, if a question is being repetitively asked then it is a design flaw. Move the button or make the process easier to understand, ask for feedback from the people posting the question.
Second, when the wrong answer to a question can create expensive problems for me, maybe I would rather get the answer from someone who is SUPPOSED to have the right answer rather then someone who might just be talking out of their ass.
Third, nothing makes me more satisfied with a product then getting great support when I need it.
I recently purchased a small consumer NAS and was having trouble with installation. Considering the failures I had with my previous NAS I was about ready to return it assuming that it was yet another hunk of junk. Instead I called the tech support number. To my utter amazement with almost no waiting I talked to a human on the same continent as me who resolved my problem immediately by pointing out a step I missed in the installation process. It was a stupid error on my part and nothing was wrong with their instructions or their product. So from now on I will recommend "Buffalo" brand NAS products to anyone that asks (they are fast as well btw).
Support can be the most valuable part of your sales team. Sales people spend a lot of money to get in front of a customer and to educate them about their product. Support calls are your opportunity to learn how to make your products better and to win customers for life.
B-School classes really should teach the importance of support departments as a sales and branding resource.
