RSS is a family of web feed formats used to publish frequently updated digital content, such as blogs, news feeds or podcasts.There is some debate as to what RSS stands for, but most people plump for 'Really Simple Syndication'. In essence, the feeds themselves are just web pages, designed to be read by computers rather than people. RSS feeds are also sometimes called news feeds.
Browser-based news readers let you catch up with your RSS feed subscriptions from any computer, whereas downloadable applications let you store them on your main computer, in the same way that you either download your e-mail using Outlook, or keep it on a web-based service like Hotmail.This is the symbol used to indicate an RSS feed.
If you click on an RSS button you can subscribe to the feed in various ways, including by dragging the URL of the feed into your news reader or by cutting and pasting the same URL into a new feed in your news reader. Most sites that offer feeds use a similar orange button, but some may just have a normal web link.
Some browsers, including Internet Explorer 7, Firefox, Opera and Safari, automatically check for feeds for you when you visit a website, and display an icon when they find one. This can make subscribing to feeds much easier. For more details on these, please check their websites.
