SpookyCash has a really complete hosted blog RSS with good spider food text and images, updating every day this time of year. We have some webmasters who really fully utilize it and some who do really well with it, but I'm honestly surprised, given how many affiliates we have, that a larger number don't make use of the feed stuff.
When I upsell other people's stuff, I've also been surprised at how rarely the feeds update and how they tend to lack either text or images.
