The Talking Brains blog is now a burned feed. Not that I know what this means exactly, but it is supposed to make it easier for people who subscribe to feeds (Talking Brains, depressing news, boring blogs, etc.) to access content easier.
So if you are already a TB subscriber, you know what to do. If you're not, but would like to be, just go down to the bottom of the main page and click where it says "subscribe to: posts(atom)". This will take you to a page that will allow you view Talking Brains on the reader of your choice.
