Actually playa your wrong, yahoo doesn't get anything from dmoz any longer, all the website links now come from google's engine. Granted there are some links to dmoz in the google database, but I doubt there are enough, and are listed high enough to get any significant amount of traffic, you may have one specific site with a set of keywords that happens to get good traffic from your listing in dmoz, but by and large that would not be the case for everyone else
I would also argue that whenever you can pay a onetime $600 fee and get anywhere from 200 to 10K hits a day, that for me convert better than 1:700 across the board, then that is a safe bet to make every day of the week!!!
Anyone else out there getting yahoo traffic ?? What do you convert at ?? Would you pay the $600 if you had to do it all over again ?? Thanks for your input!
