What is RSS?
RSS stands for "Really Simple Syndication" (or sometimes "Rich Site Summary"). It is a web feed mechanism used to publish content in websites and blogs.
RSS lets publishers (this website, for example) automatically syndicate content. This content that is provided with RSS is typically called a "news feed" or "RSS feed".
How do you use news feeds?
You, as an end user, can then use an aggregator to collect new material from a number of different websites and blogs that you are interested in and display the information in one place. It appears as if your selected websites and blogs are automatically delivering new posts to you - so that you do not have to repeatedly visit multiple websites to search out new content.
An aggregator (also called a feed reader or RSS reader) is typically an easy-to-use software program that you install on your PC, but it can also be a mobile or web-based application. Yahoo and Google offer web-based aggregators.
How do you capture a news feed?
When a website or blog offers an RSS-based feed, it typically displays this RSS logo. When you click on the logo, the RSS feed is presented in your browser. You can then copy that URL into your aggregator in order to receive automatic updates from the website in your aggregator.
