Today I have activated Feedburner Ad Network, Its really easy and useful if you have reader.
Steps : login to feedburner
2. Add your blog feeds, If you have not already added your blog feeds.
3. Select the feed where you want to display the adds,
4. Select the Monetize tab form that feed, then you will see Configure Ads
Activate FeedBurner Ad Network and/or Google AdSense for Content and then configure how you want ads to appear in your content.
In order to add FeedFlare to your blog, you'll need to insert a small piece of code near the post metadata (author, date, comments, etc) in your template.
5. Enable the activate tab and save settings.
