Over the past decade, higher education has invested millions of dollars in classroom technology. The addition of document cameras, DVD players, Internet access, and projectors (to name a few) has added new functionality to the classroom.

Most people are interested in many websites whose content changes on an unpredictable schedule. Examples of such websites are news sites, community and religious organization information pages, product information pages, medical websites, and weblogs. Repeatedly checking each website to see if there is any new content can be very tedious. Email notification of changes was an early solution to this problem. Unfortunately, when you receive email notifications from multiple websites they are usually disorganized and can get overwhelming, and are often mistaken for spam.

Notifications of changes to multiple websites are handled easily, and the results are presented to you well organized and distinct from email.

RSS is a defined standard based on XML with the specific purpose of delivering updates to web-based content.

RSS is becoming increasing popular. The reason is fairly simple. RSS is a free and easy way to promote a site and its content without the need to advertise or create complicated content sharing partnerships.
