  2. Introduction: Pull technology: browsers on client computers pull information from server machines. Browser request information Push technology: information is automatically delivered to the client Computer. You subscribe to a service such as newsfeed so that the server delivers the subscribed information. ex: RSS (Really Simple Syndication)

  3. Podcast: Podcasting: information contains audio file. Ex- iTunes

  4. Advantages/ Disadvantages for users: • Advantages • Users have control over the flow of information • No need to answer questions when unsubscribing • Spam free • Saves time • Notices & updates • Disadvantages • No photos or pictures • Too much information: traffic • Not all delivered information is wanted (Pull technology preferred) • Equality of access: need Internet connection for subscriptions

  5. Effects on Business: • Opportunities for advertisement and service • Attract more customers • Better chance of getting information on new products (ex: Amazon) • Separation from e-mail attachments • e-mail filtered as spam • updates and notices are not received • Podcast • marketers such as Audi and Warner Brothers to promote work with audio files • Ex: The movie, House of Wax • Time-sensitive information such as appointment notices and travel packages • ex: Continental and Delta airlines use RSS • Jets International: available flights and customer requests • Companies don’t know reasons for unsubscribing • Important in improving service and advertising method

  6. Social and ethical issues: Security: possibility of spyware and malware spread via RSS Richard Stiennon (director of WebrootGartner): “Spyware will latch onto RSS (Real Simple Syndication) as a way to distribute ad- and spy-style software" with further possibility of turning RSS newsfeeds into key loggers and ad spawners.“ Malware would be spread to all subscribers Privacy: Personal information extracted Companies: bad image, reputation customers lose trust rival company clients and money

  7. Effects on Education: • School notices and search feeds • school daily notices and schedule • monitor research during projects using keywords • search feeds- keywords • more access to data • Daily questions • Ex: SAT ‘question of the day’ • More likely to answer daily questions • No need to visit the websites • Share resources • Ex: http://del.icio.us (social bookmarking website) • Using ‘tag,’ keyword is related to the content • RSS feed: receive content with same tags • Class blog RSS • updates/class discussion • Equality of Access • no Internet connection: catch up with discussion or updates
