The Queen of Contextual Ads has spotted the First sighting of Yahoo Publisher Network RSS ads. On May 17, 2005 Google Began Offering AdSense for RSS Feeds, I was approved for the beta literally three and a half hours later, they looked like this but didn't always work too well.
My main concern is how Google and Yahoo! will fight with each other over a recent rss ads patent application filed by Google. I am crossing my fingers, but I hope to be able to test out YPN RSS ads on this site soon!
I posted a thread at the contextual forum, DigitalPoint Forums.
