Thanks for the note. Hmm -- the changes were designed to give the YP services much more visibility than our old thread-based listing. I'll see if I can come up with some traffic data for the new ones versus the old.
I know that we've seen quite a few new services added to the YP since the change, so the selection of services has grown. That might be having an effect. Also, most services are choosing to include a 728x90 banner ad which appears right below the service and is linked to their customer discussion thread. That might be worth looking at.
(Right now, the KBoards YP is the web's only listing of indie author services that has links to customer discussion threads, and we currently have about 175 services listed.)
Thank you and do let me know of any ideas for making the YP services more visible to interested authors and readers.
