RSS feeds allow users to subscribe to frequently updated content like blogs, news, and podcasts. An RSS aggregator collects all subscribed content from different sites into one place. Aggregators check subscribed feeds every hour and collect any new content. This allows users to check one site instead of many individual sites. RSS and aggregators are useful for managing large amounts of information by organizing content by topic and reading updates from many sources in less time. They also allow access to subscribed content from anywhere using aggregator apps. RSS should be used because it brings updated content from many sources directly to users instead of users searching various sites.
