For example

• Mint.com, http://www.mint.com/blog/ – Mint offers a RSS Feed but not a Auto Discovery feature hosted off of the home page. This option is only available to you when you visit the Feedburner hosted page.
• My.barackobama.com, http://my.barackobama.com/page/content/hqblog -  Basically the same thing as Mint.com. You only see this option on the Feedburner hosted page. And not off the home page. (I’m not even going to get into why they are not using the branded feedburner solution.)
• Whitehouse.gov, http://www.whitehouse.gov/ – They DO offer a RSS Feed and a RSS Auto Discovery option on the home page. Good deal!

This is actually pretty interesting because it’s so simply to implement and in doing so will make things easier for your readers. Part of the game plan is to get people involved, why not make it easier from then to keep up.

So anyway here some code and some links to reference if you want to add this feature to your site.
