This was a puzzling question. I think I figured out how to burn my feed in the FeedBurner, but then they told me to relocate those feeds into Google again.
Please try it and let me know if it works. There is a link to Subscribe to right on the right panel of the blog...:)
PS- I've been awfully busy and haven't been able to blog the theory. Despite of that, whenever someone asks a question, I always manage to make time and provide a brief answer. Please, feel free to ask questions.
