Using a feed reader is an efficient way of staying current on topics of interest.
RSS (Rich Site Summary, or Real Simple Syndication) is a mechanism by which a digital information source sends out links to newly added content. A feed reader lets me gather, organize, and edit these various streams of new content links in a single, user-friendly interface (I use Feedly). When I subscribe to a feed, new content is automatically sent to my feed reader as soon as it is made available, 24/7. Oh, and it’s free!
