If you decided to resurrect this 6-month old thread, could you perhaps elaborate on your answer? Why do you think it is not beneficial? Do you have a direct experience with SEO or posting on blogs and creating a campaign to study results of those actions? Have you read any documents and other case studies that suggest that? "not at all" is not really a contributory answer we are looking for as far as the standard of this board goes. You are expected to explain your position.
