Web feeds enable users to receive your news section on other websites and personal computers without ever visiting the website.  Updated news appears automatically.

Here is the technical definition from Wikipedia:

“A web feed is an XML-based document which contains content items, often summaries of stories or weblog posts with web links to longer versions. Weblogs and news website are common sources for web feeds, but feeds are also used to deliver structured information ranging from weather data to "top ten" lists of hit tunes. While RSS feed is by far the most common term, the generic "web feed" terminology is sometimes used by writers hoping to make the concept clear to novice users, and by advocates of non-RSS feed formats.

The terms "publishing a feed" and syndication are used to describe making available a feed for an information source, such as a blog. Like syndicated print newspaper features or broadcast programs, web feed contents may be shared and republished by other web sites. (For that reason, one popular definition of RSS is Really Simple Syndication.)
More often, feeds are subscribed to directly by users of online services or subscription readers called aggregators, which combine the contents of multiple web feeds for display on a single screen or series of screens.”

How does that work on your website?  Web feeds are becoming more and more common, and are beginning to be integrated into more programs.  The next version of Internet Explorer will support it, and most other browsers support them now.  All you have to do is mark your event or news item with a single check box on our system.  The website takes care of the rest. 

These feeds let people see what is going on with your website without ever visiting.  For example MSN and Yahoo let you add these feeds to your home page.  Most people use these pages as their home page.  This is the page that loads every time they open a web browser.  Right there on that page would be a list of your events and news from your website on their personal home page.  If there was something of interest in your list of news or events they could click on the link and it would open that page from your website.
