RSS is only the single greatest invention ever.
I have an RSS aggregator running all day gathering news from about 8 different sites. It's the main way I check news. Google Reader (
http://www.google.com/reader) is a great online RSS reader - for those not familiar with it.
Basically an RSS aggregator acts as an E-mail Inbox, collecting stories as they are published on the respective websites. For example, you'll get a link and part of the article, sometimes all of it, in your aggregator - kind of like how you get e-mail throughout the day. Then you just go through the "Inbox", browse by subject or topic or whatever, and read away! It's great! Best way to be up-to-the-minute on anything, really.
If you use Firefox, click the link in this post - Firefox has a built-in RSS reader - and you'll see what it looks like.
