sorry don't know why i said feedpress -- combining wordpress and feedburner
feedburner.com will actually take your blog and create an rss2.0 feed. You get a simple code to enter into your blog so people can sign up to receive your feed automatically. It was featured in Business 2.0 this month and I just got online about 5 days ago and I am a huge fan already. Easy integration, no plugins to deal with, and it works.
my feed can be seen here
http://feeds.feedburner.com/Celebridiot - that is what anyone subscribing to your feed will recieve in the rss reader or inbox
if you check out my site you can see that my rss feed icon points to that feed and the e-mail subscription box blends perfectly with my theme
