Question for the tech-minded people

How do I add a social-booking widget to my RSS feed? Its on my comments bar for when people visit the page, but as I've just checked my feed, its not showing up there. As I've had a major migration of readers to my feed lately (why? "Am I not pretty enough?" - sorry, only Aussies will get that joke ;) I thought it might be useful. I am nothing if not useful. Sometimes. I try. Remember the banjo-penis talk from the other day?. Oh, Google, now it seems all penis-talk people are coming my way. Nice. Not.
