keep up with news

RSS is a family of web feed formats. The initialism "RSS" is variously used to refer to the following standards:

Really Simple Syndication (RSS 2.0)
Rich Site Summary (RSS 0.91, RSS 1.0)
RDF Site Summary (RSS 0.9 and 1.0)
RSS formats are specified in XML (a generic specification for data formats). RSS delivers its information as an XML file called an "RSS feed", "webfeed", "RSS stream", or "RSS channel".
RSS is a simple XML-based system that allows users to subscribe to their favorite websites. Using RSS, webmasters can put their content into a standardized format, which can be viewed and organized through RSS-aware software or automatically conveyed as new content on another website.
A program known as a feed reader or aggregator can check a list of feeds on behalf of a user and display any updated articles that it finds. It is common to find web feeds on major websites and many smaller ones. Some websites let people choose between RSS or Atom formatted web feeds; others offer only RSS or only Atom.
On Web pages, web feeds (RSS or Atom) are typically linked with the word "Subscribe", an orange rectangle, , or with the letters or . Many news aggregators such as My Yahoo![1] publish subscription buttons for use on Web pages to simplify the process of adding news feeds.
