  14. Issues Social Networking: An Internet Addiction? • Have you heard of the term Internet Addiction Disorder? What about Facebook Addiction, Internet Junkie, Net Junkie, or Nethead? Any of these labels sound familiar? • What about "online-a-holic?” 

  15. Issues

  16. Issues • There is often a disconnection between students' desire to protect privacy and their behaviors; teens are not aware of the public nature of the Internet. • Trust and usage goals may affect what people are willing to share. • Facebook users express greater trust in Facebook than MySpace users do in MySpace and thus are more willing to share information on the site. Privacy

  17. Issues • Jagatic, Johnson, Jakobsson, and Menczer (2007) used freely accessible profile data from SNSs to craft a "phishing" scheme that appeared to originate from a friend on the network; their targets much more likely wanted to give away information to this "friend" than to a perceived stranger.

  18. Issues • Teens are aware of potential privacy threats online and many are proactive about taking steps to minimize certain potential risks. • 55% of online teens have profiles, 66% of whom report that their profile is not visible to all Internet users (Lenhart & Madden, 2007). Of the teens with completely open profiles, 46% reported including at least some false information.

  19. Issues According to Maressa Orzack, director of the Computer Addiction Study Center at Harvard University's McLean Hospital, between 5% and 10% of Web surfers suffer some form of Web dependency. Addiction

  20. Issues The age group that dominates social networking sites is 35 to 44, and only 3% are aged 65 or older.  Some of those users are spending 8 billion minutes online at Facebook alone - sending daily messages, joining groups, tagging photos, updating one's status, sending and accepting friend requests, creating and managing farms, and decorating rooms - it's a fairly long and time consuming list.  Who dominates social networking?

  21. Issues • Nearly half of six to 11-year-olds spend one to two hours per day using the internet to play games but only 10 percent use the internet daily to do their homework. • 50 percent of children aged between 12 and 17 use social networking sites every day while only 16 percent use the internet daily for homework. Children

  22. Issues Many people unconsciously use the fantasy world of the Internet to escape unpleasant family dynamics, drug abuse, alcoholism, or stressful work-related conditions and often turn to the Internet and social networks for comfort, familiarity, or support. Reasons for addiction

  23. Issues • The average person has in fact double the amount of online friends than physical ones, according to research commissioned by the Cystic Fibrosis Trust, which found users of such sites have 121 online friends compared with 55 physical friends. Do social networks ruin true friendships?

  24. Issues • People tend to be more open, confident and honest with their virtual friends than their "real" counterparts. • One in 10 people has either met their best friend online or believe they will meet lifelong friends on the web.

  25. Issues • Do not post private information, including your cell phone number, home address, class schedule, social plans, etc. unless you are prepared for anyone to find you/track you down, any time of the day or night. How to stay safe

  26. Issues • Do not post anything that might be embarrasing to you in a potential employment situation. • Adjust your privacy settings so as to control who has access to your personal information
