That's why I often chime in and try to help even if I'm not having the problem, so that people can have more data points. It helps to know whether it's a common issue, whether someone has already figured out a workaround or whether it's something to contact support about. It also lets prospective buyers get a sense of the likelihood they'll have to worry about that problem.

Don't get me wrong, a problem is a problem for the user and they SHOULD mention it and they deserve to get support. But if it's a rare problem, that doesn't necessarily have to influence whether or not someone decides to purchase. I know before I make a purchase, I always check out the help/support sections of the product's website and my primary goal is to figure out how much trouble people generally have and how serious these problems are.
