Anyone can sign up for Facebook and interact with
the people they know in a trusted environment.

19. • Twitter is a social networking and microblogging
service that allows you answer the question, "What
are you doing?"by sending short text messages 140
characters in length, called "tweets", to your friends,
or "followers."

20. Viadeo is a professional social network with
over 40 million members. Viadeo is used by
those who want to:

• Manage and develop their network of
professional contacts

network with over 120 million members and

knowledge, ideas, and opportunities with a
broader network of professionals.

27. "Our evidence suggests that
social media carried a cascade
of messages about freedom
and democracy across North
Africa and the Middle East, and
helped raise expectations for
the success of political
uprising,”

28. The “Arab Spring” in Tunisia, Egypt and elsewhere in
the Mid-East heavily relied on the Internet, social
media and technologies like Twitter, TwitPic, Facebook
and YouTube in the early stages to accelerate the social
protest. There is less evidence that social media played
as strong a role in places like Yemen (where Internet
penetration is low or Libya where the government
cracked down on the Internet more effectively.

29. Because networking in online social
communities is still a relatively young online
trend, whether or not social networking is
harmful is still unknown. Like any other type of
networking or social club with which individuals
become involved, it is a good idea to do your
homework and make sure that you know what
you are getting into. Understand the terms of
use, the rules and regulations, and be clear on
issues like security and privacy.
