I have a few feeds here:
Joint feeds of everything should follow later on.
Feeds let you follow the changes on a Web site, without having to keep coming back just to see if anything has changed. They let you use the content published as a feed in a way that is convenient to you, automatically.
Crucially, publishing feeds has become very popular; lots of sites let you look at their content this way, and so there are plenty of readers for practically every platform.
I use Google Reader, but there are lots of alternatives. Play with an RSS reader, to get a feel for what you get.
