I just wanted to relate my experiences in dealing with YPN staff thus far ...
I have sent a couple of emails to them, asking about several things that I couldn't find in their TOS ... To my surprise, I got ultra fast replies (within a couple of hours) both times. Also, they told me not to hesitate to call them (gave me a toll free number) if I had a question that needed immediate attention! So I called them yesterday with a question concerning ad unit placement. I didn't have to hold more than 15 seconds, and the YPN rep "walked me through" what I needed to do over the phone, and checked it. I even got an email confirmation about an hour later!
YPN needs to be immediately commended for the great attention they are giving to publishers ... This, added with Overture's already massive ad inventory, and all around ease of use, spells BIG trouble for Adsense!
superior customer service, yes. but massive ad inventory, this i've yet to see. i'm in an industry with loads of ads yet all i see are the same ads over and over again. my adverts have not changed at all since the program was opened
