FeedBurner announced today a new service, that allows you to insert Amazon ads into your RSS feeds.

If you use the service, any purchases made through visitors clicking the links will earn you a percentage of the sale, which will be credited to your Amazon Associates account.

I saw recently that another service from WayPath, Blender, allowed the addition of the Amazon ads into your feeds, but it was only launched as a test, and you couldn't add your own Associates ID to earn from the ads. (The option is there now)

I discovered Feedburner a few months ago, and they keep coming out with the coolest features for RSS feeds; how it works is you add your current feed (any version of RSS or Atom) to Feedburner, which "burns" the feed into a version that will work in any reader.

Then, through an extremely simple enhancements page, you can add on any of the extras you like, such as making those ugly XML files friendly to the eye, or splicing your Flickr & del.icio.us items into one single feed.

This Amazon idea looks pretty cool for people who would like to try monetize their feeds.
Also new is the ability to add a Creative Commons license into your feeds. For any bloggers or site owners who publish RSS, I would highly recommend checking out Feedburner; it's free to sign up and the extras you get for your feed are very useful.
