| [09:42:55] Julian Bond says: Just been pondering group forming. For a network of size N - Metcalfe: Value grows by N^2 - Reed: Value grows by 2^N - N - 1 Some implications for Skype:- - Group chats radically increase the value of the network because they move Skype from Metcalfe to Reed. - What's the minimum average size for a group chat to be self-sustaining? - What's the maximum average size for a group chat before it splits? There's some law that says groups become unwieldy at about 150 participants. So Skype public chats should be set to max 150 ? [09:42:55] Julian Bond says: - Skype needs to actively encourage group forming. Which means things like public chat directories. [09:43:49] Julian Bond says: Few-To-Few comms are more interesting than one-to-many or many-to-many [09:44:37] Julian Bond says: "The long tail" is spiky. It's actually made up from large numbers of small communities. [09:44:49] Julian Bond says: In any community, 90% lurk. [09:45:37] Julian Bond says: The Fat Middle is more interesting than the Short Head or the Long Tail. [09:45:38] Julian Bond says: Oooh. I can feel a book coming on. |
