Feed2Podcast automagically turns your blog - or, more importantly, any RSS feed - into an audio podcast.
The podcast uses one of those text-to-speech engines that are popular among the fitter, happier, and more productive crowd. You can listen to the podcast in a streaming flash player, or you can subscribe to the podcast's RSS feed. Feed2Cast is a very cool way to get started in the podcasting world without all that pesky talking.
UPDATE: You can listen to a Feed2Cast sample of Lifehacker.
