RSS

Really Simple Syndication (RSS): An XML-based web feed format for standardized content distribution and real-time aggregation.

RSS (Really Simple Syndication, or Rich Site Summary) is a foundational web feed technology: It utilizes a standardized XML file format to publish frequently updated content, like news headlines, blog posts, or podcast episodes. The system allows a publisher to create an RSS document (a 'feed'), which is then monitored by a user's news aggregator (an 'RSS reader') such as Feedly or Inoreader. This process eliminates the need to manually check multiple sites: Users receive timely, consolidated updates directly to a single interface, ensuring efficient, personalized information consumption.
