Let's say you have a friend who writes a blog that you enjoy reading. Your friend writes pretty regularly, but it's not like he updates his blog every day. You don't want to go to his webpage every single day to see if he's got a new posting, but if you don't go pretty regularly then you will miss a lot of it. RSS fixes all of that.
RSS stands for 'Really Simple Syndication.' It sends things from the internet to things called 'aggregators.' An aggregator is a program that collects the different feeds you subscribe to all in one place. So, I can get the blog posts from your friends blog sent to your aggreator, and every time your friend posts, you know about it right away.
You can subscribe to any number of different things. Lots of websites allow you to subscribe to their material in RSS form. The symbol for RSS looks like this:


Anyway, there are several different RSS aggregators, but my favorite is called Google Reader. You can find it at google.com/reader. It's easy to add new feeds and it's easy to navigate. Here is a screenshot of what my Google Reader page looks like, looking at today's Get Fuzzy.

The disadvantage of Google Reader is that it's web based. You have to go to that website in order to use it. For Mac users, Apple Mail will get RSS feeds, but I don't really like how it works that much. I recently discovered a program called Vienna that collects RSS like a mail program does, but does it in a better way. I like it because I don't have to go on a web browser to get my feeds, and it will run in the background. When a new article appears, it shows up in the bottom of my screen like a new email would. Here's the same Get Fuzzy comic as it appears in Vienna.
