Agreed, i had 2 sites submitted that i paid for several years ago and whilst the traffic used to be worth it, it soon stopped, almost as if someone turned the 'sales' switch off overnight.

Instead, try getting a site or two listed in Dmoz.org and wait for Yahoo to update their directory that way, although to be fair, Dmoz takes forever and a day to get a site accepted these days which is a real shame because after Google they used to have some pretty good traffic levels if you hit the right category, with the right editor.
