What is an rss reader used for? for creating a user account on a social new site

RSS which stands for Really Simple Syndication or Rich Site Summary is a way to have information easily delivered to you instead of making an effort to go look for it. With so much information and new content on the web popping up daily, it can be difficult to keep up. With an RSS feed, you will automatically stay informed by retrieving the latest content from sites you have an interest in and this will save you time.
