Dialyn, I would think that if a merchant has a product that answers a question or provides a solution for somebody, they should definitely mention it or include a picture or suggest a link, etc. I don't think the goal was to prevent the existence of advertising, but rather to organize the Renderosity site in a more meaningful manner, so those looking to learn about or purchase products can do so without weeding through conversation, and those looking to discuss Poser usage and techniques can more easily get answers to their questions or share useful information without weeding through products for sale. Sometimes these will overlap, of course.
