Ãœberdesigner Chris Pearson has a great article on his site about feeds. He’€™ll let you in on how to offer a feed for you main content, and one for your asides ‘€“ or whatever you’€™re calling that extra fluff that you keep pumping out.
The article is for WordPress, and can be used with or without Feedburner. I personally recommend the latter, burning feeds through Feedburner gives you access to great statistics.
Go read the article on multiple feeds now!
Oh, by the way, some shameless self-pimping. Also be sure to check out the Chris Pearson interview over at Bloggertalks. It’€™s a good read with lots of interesting tidbits from a designer’€™s point of view.
