What is RSS Feed?
RSS or Really Simple Syndication is a useful tool for keeping updated on your favorite websites. RSS makes use of an XML code that constantly scans the content of a website for updates and then broadcasts those updates to all subscribers through a feed.
In order to receive RSS feeds, you must have an aggregator, a feed reader. There are a number of aggregators online, many of them free, so with a little bit of searching, you should be able to find an interface that appeals to you. In addition to being available on your computer, RSS feeds can also be read on PDAs and cell phones.
When you come across a website you would like to add to your aggregator, you can do so in one of two ways. Most sites that offer an RSS feed have an "RSS" or "XML" button on their homepage that you can click on and it will instantly add that feed to your aggregator. Depending on your aggregator, you may instead need to copy and paste the URL of the feed into the program.
