Getting started with Feedburner

http://www.google.com/support/feedburner/

Feedburner enables you to expand the reach of your website or blog. People can subscribe to it and receive updates by email, through a news reader, or via a web portal like iGoogle or My YAHOO. You can also deliver your content as widgets for cell phones and other mobile devices.

Signing up for Feedburner is a snap. Yes, it is owned by Google, and yes, I think that is nothing but good. But those who dislike Google will likely want to use digg or some other service.
