Not that you need it, but you can enrich your mind and impress people at cocktail parties by subscribing to daily feeds that send along a Word Of The Day (via Wordsmith.org), Quote of the Day (via Brainy Quote), or how about a bit of wisdom with a daily fortune cookie? Just look for the RSS or XML links on each page to get the feed to add to your news aggrigator.
RSS (Real Simple Syndication) is technology that allows certain programs called RSS readers to download new content from an RSS feed to your computer. RSS feeds are often found on blogs or forums and contain the latest posts to that blog or forum. An RSS feed can also be found on news sites and contains the latest articles found on that site. Just like an email program such as Microsoft Outlook saves you time by checking for new mail for you and downloading it so that you can view it, the RSS reader checks for updates for you and as soon as it sees an update, it will download it to your computer and can notify you by a popup message or dialog, etc.
