feedburner + overture not working

Hm, doesn't sound like the FeedBurner/Overture combination is doing very well:

Since I'm on the topic of Boing Boing, we've been testing Yahoo's long tail RSS ads. It's tough to find ads that are relevant to Boing Boing's content, and often the program fails - defaulting to pretty random ads. But when this combination hit my RSS aggregator, I had to note it....

This is predictable - keyword search driven ads probably aren't as lucrative as directly placed ads for medium to high traffic websites.
