I think there are several things that go on in terms of comparing your work to others, but I don't think that the pricing metric is one I would ever want to see laid out. Most people state in their profile whether or not they sell, if it makes you feel better to know that someone is making something without an eye on the bottom line. But does it? Everyone has a different skill set, a different market, or no market. I do my work to feed my soul and hopefully inspire others. Other people are making birthday cookies. I've seen birthday cookies that inspire my soul, and I hope that they cost a pretty penny, too. There are a million reasons why I think how much the cookies cost is neither here nor there, but an international public cookie forum is the last place I think this sort of thing would be appropriate.
