Feedburner is now owned by Google. You should, if you do not have an account. This is especially helpful for folks using Blogger platforms because it is another way of getting stats for your site. So go and study the site. Activate some of the features. If you want a tutorial or two about it let us know.
Feedburner can also generate the link that allows folks to subscribe to your site and be alerted when you post via email. This is great for many who are not using RSS readers yet.
