I agree with Jamal. It depends on the value of the site and where you are in
SEO. If you have no good links, and no way to hget them, then directories are of value, Yahoo being no exception. The problem with both Yahoo and DMOZ is ifyou are in them, your SE description will be pulled from your directory description (usually not very good), so if you are well on your way on linking, forget both Y and Dmoz..
