From last few month I`m constantly monitoring peoples thought on Dmoz Directory . The largest human edited directory , i`m sorry to say but it`s just isn`t worth !!
Just browse through any category , ANY! you`ll find thousands of webpages that isn`t worth to be listed. Say in web design section, you`ll find pages by kids who have made for just for fun on free site and got listed . And the usefull ? yeah they`ll get listed , don`t worry ! maybe in next 20 years they will.
