RSS stands for "Really Simple Syndication." It's a format that web sites and blogs can use to send updated headlines to you via services like My Yahoo!. My Yahoo! gathers the content you select from a variety of sources and displays it for you in one convenient location. Syndication means you don't have to visit each site individually to see what's new -- you simply scan headlines or brief article summaries and click to read the full text. That's the "really simple" part. And it's "really simple" for publishers to make their content accessible this way too.
RSS is an easy way for you to keep updated automatically on websites you like. Instead of you having to go to websites to see if they've written a new article or feature, you can use RSS (which stands for Really Simple Syndication) to get them to tell you every time they have something new.
Different News Readers work on different operating systems, so you will need to take this into account when you make your choice. The easiest way to have your RSS feeds sent to you is to open a my Yahoo or a my MSN account. Then all you have to do is add the content you want delivered to you.
