I’ve noticed something today after a post over at webmaster-talk.com. Apparently Feedburner chooses to show two different types of feeds even under the same URL. I’m not sure what it was that triggers one or the other, or how to even fix it, but I have noticed that one of the source code feeds is in HTML whereas the other is in XML. Is this an error in Feedburner and what makes it determine which one to show? Anyone know?
