I have been considering putting an article directory with relevant articles on my real estate classified site. I only want quality articles not just random rubbish. The site already has a forum that doesn't get much use, I am considering rather than creating a new directory, using the forum to post articles. This will also allow more user feedback. An option I am also considering is allowing people to post relevant articles on the forums with back links, but moderating gratuitous spam posts. Basically I want quality as much as quantity. What do people think of this idea? Also on another note, from SEO perspective is www.mysite.com/forums much better than forums.mysite.com or doesn't it make much difference?
