- ....the size of the human brain allows stable networks of about 148 (personer alltså - min komplettering). Rounded to 150, this has become famous as “the Dunbar number”.
- .....the Roman army, seem to be organised around the Dunbar number. Because everybody knows everybody else, such groups can run with a minimum of bureaucracy.
- ....sociologists also distinguish between a person’s wider network, as described by the Dunbar number or something similar, and his social “core”.
- The Economist asked Cameron Marlow, the “in-house sociologist” at Facebook, to crunch some numbers. Dr Marlow found that the average number of “friends” in a Facebook network is 120, consistent with Dr Dunbar’s hypothesis, and that women tend to have somewhat more than men.
- Men......the number of people on an individual’s friend list with whom he (or she) frequently interacts is remarkably small and stable.
- Thus an average man—one with 120 friends—generally responds to the postings of only seven of those friends by leaving comments on the posting individual’s photos, status messages or “wall”. An average woman is slightly more sociable, responding to ten.
- When it comes to two-way communication such as e-mails or chats, the average man interacts with only four people and the average woman with six.
- Lite av en slutsats: What mainly goes up, therefore, is not the core network but the number of casual contacts that people track more passively......Put differently, people who are members of online social networks are not so much “networking” as they are “broadcasting their lives to an outer tier of acquaintances who aren’t necessarily inside the Dunbar circle,...”
- Humans may be advertising themselves more efficiently. But they still have the same small circles of intimacy as ever.
Alltså: Facebook som en sorts personlig mediekanal till kontakter i periferin. Jag finns alltså är jag.
