Social Network Site

"A "social network site" is a category of websites with profiles, semi-persistent public commentary on the profile, and a traversable publicly articulated social network displayed in relation to the profile.

To clarify:

1. Profile. A profile includes an identifiable handle (either the person's name or nick), information about that person (e.g. age, sex, location, interests, etc.). Most profiles also include a photograph and information about last login. Profiles have unique URLs that can be visited directly.

2. Traversable, publicly articulated social network. Participants have the ability to list other profiles as "friends" or "contacts" or some equivalent. This generates a social network graph which may be directed ("attention network" type of social network where friendship does not have to be confirmed) or undirected (where the other person must accept friendship). This articulated social network is displayed on an individual's profile for all other users to view. Each node contains a link to the profile of the other person so that individuals can traverse the network through friends of friends of friends....

3. Semi-persistent public comments. Participants can leave comments (or testimonials, guestbook messages, etc.) on others' profiles for everyone to see. These comments are semi-persistent in that they are not ephemeral but they may disappear over some period of time or upon removal. These comments are typically reverse-chronological in display. Because of these comments, profiles are a combination of an individuals' self-expression and what others say about that individual."

4. Conversations - a way of talking to other people through the system

5. Groups - a way of forming communities of interest

Geographical Spread

From a world map of social network sites at http://valleywag.com/tech/data-junkie/the-world-map-of-social-networks-273201.php

"* Orkut leads in the Indian subcontinent, as well as Brazil;

• Facebook is stronger, internationally, than Myspace, with surprising strongholds in the Middle East;

• hi5.com is the most international of all the social networks, leading in Peru, Colombia, Central America, and other, scattered countries such as Mongolia, Romania, and Tunisia;

• both Bebo and Skyblog follow colonial patterns, the first strong in smaller English-speaking countries such as Ireland and New Zealand, and the latter in Francophone countries;

• and Friendster, the original social network, leads all across Southeast Asia.

• Fotolog, a photo service defeated in the US by Friendster, has re-emerged as the dominant social network in Argentina and Chile."
