Eric Lefevre has just put together an aggregated feed of various blogs (including this one!) that discuss techniques and best practices related to the field of Continuous Integration and agile testing in general. You can subscribe to it using this Feedburner link: http://feeds.feedburner.com/CitconBlogs.
