Syndication/OPML/RSS

Anybody out there know what these things at the right of the main Blog page, "Syndication" and "Opml" are?  I gather it's for some sort of "news" feed or push or something, but it's new to me.  It came as part of the free Forum package from the hosting service, so if it works great, and if not, oh well...but I'd like to learn a little more about it and see if it's useful or just another time-consuming Web "feature".
