Question of a day: where to put a message?


Just got this pic in my twitter from Valdis Krebs:

Where to put a message in a social network?

I’ve decided for Heather, and let me explain:

  • this person isn’t the most interconnected:
    • Diane – 6 connections,
    • Fernando, Garth – 5,
    • Andre, Beverly – 4,
    • Carol, Ed, Heather – 3,
    • Ike – 2,
    • Jane – 1.
  • Diane is the most obvious selection – she has the highest centrality (where n = 10, deg(v) see before as connections’ count):

Centrality formula

    • Andre – 0.4,
    • Beverly – 0.4,
    • Carol – 0.3,
    • Diane – 0.6
    • Ed – 0.3,
    • Fernando – 0.5,
    • Garth – 0.5,
    • Heather – 0.3
    • Ike – 0.2,
    • Jane – 0.1.
  • but she’s the only connection with the shortest path –┬áthe maximum route length (thus also message distributing speed) will be:
    • for Diane – 5 nods,
    • for Heather – 2 nods.
  • And the winner is… Heather! (as the fastest message spreader).
