I've gotten this survey before and was paid for it.
I'll fill it out again.
I would prefer they just ask you to name five things you like and five things you dislike.
I can guarantee the #1 response on the disklikes is ad relevancy.
There are relevant ads for my website - when I look at how my website is listed in Yahoo, for the specific terms and content my site has, there are very relevant (and plentiful) ads for my topic(s) that show up.
If you visit my site, you get things like mortgage ads, which have nothing to do with my site. People aren't getting to my site because they are interested in mortgagees, they are getting to my site because they are interested in the widgets I talk about.
Said widgets do not show up in any YPN ads on my site. Said widgets do show up in ads when I go into Yahoo search and look for my site.
It's almost like Yahoo is saving relevant ads for their searches, and the ads they are serving us are completely different.
Every few weeks, I try out YPN for a few days. I don't know why Google can take a site that has never had AdSense on it, and within hours (if not sooner), it will be showing relevant ads.
Meanwhile, Yahoo, on the other hand, I can run YPN ads for days, and they still spit out the same damned mortgage ads :-(
