RSS, or Really Simple Syndication, is a web feed format that allows users to receive updates from their favorite websites without having to visit each one individually. By subscribing to an RSS feed, users can get the latest content, such as news articles or blog posts, delivered directly to their RSS reader. This makes it easier to stay informed about topics of interest. RSS feeds are typically represented in XML format, which is a structured way to present data. Many websites, including news outlets and blogs, offer RSS feeds, allowing users to customize their content consumption. Popular RSS readers include Feedly and Inoreader, which help organize and display these updates efficiently.
