One way of keeping up with new SEO trends, developments, and techniques is to listen to the experts. Moderator Disa Johnson strikes a delightful balance between silent supervision and direct contributions. She'll often throw another perspective on a post, or gently correct or expand on a comment or suggestion, but she doesn't ride roughshod over proceedings like other star moderators might want to.
What is truly great about Search Return is that it's honest and ethical, though without being too prissy about open debate. Disa's attitude is clearly a 'play fair by the search engines and they'll play fair by you' one. Some of the discussions can get quite technical, too technical perhaps for many folks (me included). But persevere if you feel that way too - there's plenty of good stuff for all levels of interest and expertise.
