Two ways to subscribe to a blog, Twitter
 stream or any other stream of events


          You receive an email whenever a new
          item is posted.




          New items are periodically downloaded to
          your RSS reader.
RSS is really simple

                    A program you install on
                    your computer




                   A program that is
                   downloaded by your

                   visit the Google Reader
                   Web site

Many other directories and aggregators
      RSS feeds for any event stream
       for example when someone

•   Adds a new appointment to their calendar
•   Posts a reply to a forum post
•   Adds a record to a database
•   Places an order for a given product
•   Ships an order
•   Mentions your name in a company email
•   Posts an image on Flickr
•   Tweets
