social networks

five key points learning in past lecture are
1. When technologies connect or separate people, they become media.
2. Technologies embody social, political, cultural, economic and philosophical ideasand relationships.
3. When a medium is new, it is often used to simulate old media.
4. New media do not replace old media, they displace them.
5. People make media and then media make people.

This week, we learned about 'social networks'.
Key points of this week are
•New media technologies usually reinforce existing social networks or even work to isolate people.
–examples?
•(BUT) When new media technologies facilitate new social networks, they simultaneously challenge existing social, political and economic relationships.
–examples?

Social networks as science
-social network analysis is an interdisciplinary social science, but has been of especial concern to sociologists
Social networks as technology
- email, newsgroups, and weblogs
- in the design of the arpanet (the forerunner to the internet) email was an afterthought!
Social networks as popular culture
-their identity and connect in personally meaningful ways
Social networks as art
-It express relationship each other as art

This week lecture understood a little.
I am interested in lecture about social networks but English lecture is difficult as ever.
