Directory Listings



I think it is still worth to pay yahoo directory listing, since I see most of the sites got a better position in SERP. But you must consider that yahoo directory listings is just one of thousands factors in SEO.
 
I would say it depends on the site. If the site is an affiliate site don't think it would be worth it. However if this is a quality site that you plan on keeping and maintaining then by all means. My 2 cents...
