What if you could tell a website to let you know every time that they update? In a sense, this is what RSS does for you.
RSS flips things around a little and is a technology that provides you with a method of getting relevant and up to date information sent to you for you to read in your own time. It saves you time and helps you to get the information you want quickly after it was published.
RSS stands for 'Really Simple Syndication'. Many people describe it as a 'news feed' that you subscribe to.
I find the 'subscription' description helpful. It's like subscribing to a magazine that is delivered to you periodically but instead of it coming in your physical mail box each month when the magazine is published it is delivered to your 'RSS Reader' every time your favorite website updates.
How RSS actually technically works is probably a lesson for another day but the key today is for you to understand why it's good and how to use it.
Let me say right up front that I'm not the most technically savvy guy going around – but even I can use RSS. At first I found it a little strange to make the change from bookmarking to RSS but I found that when I started that I just couldn't stop.

It seems to a brilliant post about rss.
Thank you for this input.

Content of some of the websites totally depends on the RSS. All the websites and business list products on eBay store are based on Products RSS feed and list the same products on remote site with use Of products feed. Same way advertising your entire product inventory can be listed on merchant sites with use of product feed only no other specification or documentation so this way RSS has brought good changes in the industry which have reduced lots of work .
