RSS or Rich Site Summary is a technology that is being used by number of users to keep track frequently updates on their adored websites.
We had to bookmark websites in our browsers and had manually return to them to view its new updates which was very complicated when we try to track many websites at once also if we forget to check bookmarks we missed all the information.
But now RSS automatically delivers regularly changing web content. Now a days many news-sites, weblogs and other online publishers organize their content as an RSS Feed to their regular viewers.
RSS provides you with a routine of getting consistent and up to date information sent to you that you can read in your own time.
