Google Reader

 
Who could explain this better than one of the Google Engineers?  Click on the logo above to go directly to Google Reader and watch the video made by Chris Wetherell.  He does a very good job of making sense of RSS technology.

If you blog, like to read blogs, or have teachers who blog, Google Reader will aggregate all of the information for you in one simple to use page.  Think of it as an online magazine subscription, except that it's free and you don't have to walk down to the mail box to get your stories.  Google Reader does it all for you, and will even put an easy to use icon on your Google Toolbar so you can easily add content.
