There are a couple of feed options I've added for BlogWatcher that might require a little explanation. They both work with the concept of "tagged" content.
Tagging is one of the "hot" new topics in blogging. When new posts are made in a lot of software (including mine) the author can tag it with whatever keywords seem relevent to them. There are then services that allow you to search for content that has been tagged with words that interest you.
