RSS:

The trouble with living in the Information Age is paradoxical: There's too much information. It's everywhere. How are you supposed to keep track of all the news, sports, weather and blogs you follow? Better yet, how are you going to do that and find time for work, school and family?
If you're addicted to the constant flow of data that we know as the Internet, you're not going to be able to manage it without some help. One way to keep track of it all has grown very popular since its introduction in 1997: RSS. Short for Really Simple Syndication, RSS is a way to subscribe to a source of information, such as a Web site, and get brief updates delivered to you.
These sources are called feeds. When you subscribe, you'll get a feed -- often a series of headlines and brief summaries -- of all the articles published on that particular Web page. This lets you scan the articles on the page more efficiently. Sometimes you'll even spot more headlines that you might never have seen buried on the original page.

Reading RSS feeds can be a great time-saver. In the time it takes you to scan whole Web pages for information, you can review headlines from dozens of sites all collected in one place. On the other hand, the ease with which you can view RSS headlines may convince you that you can subscribe to even more sites. You may end up spending just as much time reading feeds as you used to on regular Web sites.
