I've been burning feeds - not something i thought i'd be saying in a marketing role + it's free!
Recently Google purchased news-feed management company FeedBurner for $100 million and Google is now offering the service for free - Google Gives Away Feedburner
Why Would I Want to Set Fire to my Feed?
If you long for creative ways to attract an audience, see where your content goes once you publish it and generally add a lot more value to your feed, then "feedburning" is for you
Your "feed" is redirected so that you can get a true picture of how many subscribers you have, where they come from etc. You are provided with a very detailed analysis which can be tailored to what you require. I've used the data on one blog to help promote the other blogs. It's interesting to see where your traffic comes from and where it is going to!
