...an article I got from Walter without any reference to the author.
Two facts the article mentioned I found particular interesting:
- News Corp. was paying a huge amount for facebook
- Seok Kang found out, that online chat has a negative effect on social psychological well-being  - "online interaction with a lack of non-verbal cues leads to offline loneliness and depression".
 Seok Kang. Disembodiment in online social interaction: "Impact of online chat on social support and psychosocial well-being". Cyberpsychology & behavior, 10(3), 2007
