RSS stands for Really Simple Syndication and Rich Site Summary. It allows users to subscribe to feeds from websites, blogs, news sites and more to get automatic updates without having to visit each site individually. Some popular RSS readers include Google Reader, FeedReader and NetNewsWire which allow users to organize feeds and access updated content in one place from any device. Using RSS in education can help students stay up to date on topics, share resources and ideas through blogs and collaborative tagging of sites.
