To reply to the OP. I would say that it is a result of people not knowing that you are the go to or not taking the time to thoroughly peruse the site and find out where to go. The scenario is usually something like... Customer has problem, Customer Googles websites dedicated to the product they are having a problem with, Customer scrolls down and sees product sub forum, in this case (VZ-58), Customer posts problem.
So while it is usually frustrating for both parties, I don't think it's intentional.
