3. 1. Introduction

4. Context • MySpace, Facebook and similar sites are amongst the most popular web sites • According to HitWise, in 2007 MySpace overtook Google in the US Facebook has overtaken MySpace

5. SNS definition • A web site allowing individuals to • construct a public or semi-public profile within a bounded system • articulate a list of other users with whom they share a connection • view and traverse their list of connections and those made by others within the system boyd, d. m., & Ellison, N. B. (2007). Social network sites: Definition, history, and scholarship. Journal of Computer-Mediated Communication, 13(1), article 11.

6. Friends Not all friends are friends! Some are not even acquaintances, family members, colleagues

7. Why have sns friends? (1/2) • It would be socially inappropriate to say no because you know them • Having lots of Friends makes you look popular • It’s a way of indicating that you are a fan (of that person, band, product, etc.) • Your list of Friends reveals who you are • Their Profile is cool so being Friends makes you look cool boyd, d. (2006). Friends, Friendsters, and MySpace Top 8: Writing community into being on social network sites. First Monday, 11(2)

8. Why have sns friends? (2/2) • Collecting Friends lets you see more people • It’s the only way to see a private Profile • Being Friends lets you see someone’s bulletins and their Friends-only blog posts • You want them to see your bulletins, private Profile, private blog • You can use your Friends list to find someone later • It’s easier to say yes than no

9. Friends • Friend news (Facebook)

10. History After a slow start, many successful SNSs emerged – then other sites began adding SNS services or innovating for niche markets boyd, d. m., & Ellison, N. B. (2007). Social network sites: Definition, history, and scholarship. Journal of Computer-Mediated Communication, 13(1), article 11.

12. Facebook dominant? Google search volume

13. 2. Examples of social network sites

14. Three types of social networking site • Socialising SNSs - for recreational social communication between members • Networking SNSs - for non-social interpersonal communication (e.g. LinkedIn) • (Social) navigation SNSs - social network features to help users find information or resources (e.g., YouTube, CiteULike)

15. Types of SNS

16. Examples of SNS • LinkedIn • Gaia Online • CyWorld • Digg • Last.FM

17. LinkedIn • SNS designed to help members find new business contacts • Especially helps look for friends of friends or aquaintances of acquaintances

20. Cyworld • Korean SNS • Avatar-based –users live in their own home in their mini-hompy • Arguably the world’s first popular SNS • Members meet new people online • Members seem to self-disclose online and make trusting relationships • Micropayments via “acorn” currency

21. Digg • “a place for people to discover and share content from anywhere on the web” (digg.com/about, May 4, 2008) • Can navigate stories by friending people who post stories • Digg is not really for friendship.

23. Can friend LewP and navigate his stories (can also do this without friending) and friends • LewP is a human “recommender system”?

24. Last.FM • Music-based site • Helps members listen to music that they like or might like • Prompts users to friend people listening to similar music • Can find new music liked by others with similar taste

26. 3. Cybermetric case study of MySpace Illustration of a range of types of “extractable” public information about MySpace members

27. MySpace members data sets • random sample of 15,043 members • systematic sample of 7,627 members who joined on July 3, 2006 • excluded: music sites, ex-members, members with 0 or 1 friends all information on home pages was automatically downloaded and harvested by SocSciBot -> Excel

28. days since last access -members use MySpace once or frequently all Members >>

29. days since last access -members use MySpace once or frequently July 3 members

30. MySpace “age” profile:average “age” is 21

31. younger members have more MySpace friends

32. gender factors • female users more likely to be “here for” friendship and male users more likely to be “here for” dating (but only a minority) • males and females both preferred to have more female friends and top 8 friends • females preferred a greater proportion of female Top 8 friends women make the best friends! (403 data set)

33. who swears most? • for US MySpace home pages: • male = more likely to contain strong swearing • for UK MySpace home pages • male = more likely to contain moderate swearing • no difference in strong swearing - possibly more strong swearing in female home pages in the younger age groups • apparent reversal in gendered strong swearing in the UK for young people >> July 3, 2006 members, extended collection

34. percentage of profiles containing swearing (typical sample size 20-148 for non-web swearing research)

35. Conclusions • Social network sites vary by country and type • Some sites with SNS features can help users find information (e.g., pictures, video, music, news) by navigating people rather than documents/objects • “Friends” may also give specific advice, if asked nicely (as Lay Experts or even LIMs?)! • Should librarians routinely suggest SNSs as an additional source of information – even emotional support?
