RSS allows users to subscribe to frequent updates from websites and see condensed summaries of new content without visiting each site individually. An RSS aggregator collects feeds from multiple sources into a single location, making it easier for users to stay informed by accessing many updates at once in a brief reading session. RSS feeds share common information with their originating websites, including updates to post dates, author names and the option to select specific articles to read so users can focus on the most relevant and useful information.
