I have been working for a while on the idea that a message moves through a culture not only because it is a good message or perfect frame BUT ALSO because the base is connected. Network-centric advocacy rests to some degree on the idea that connectivity is essential for swarming, mobilizing, fighting message control and dominating public debate. It is essential that message and advocaacy efforts are formated so they can "move" from listserves to cell phones.
Here is the example that helps to demonstrate the power of connecctivity. If you think of messages much like fire ..even the perfect message (ie. i tell you you tell the other you know with perfect clarity, they tell others) connectivity matters.
Here is a screencast (my first) of a Netlogo demonstration of fire spreading in a forest. I work over the density of the forest and run the program a few times. You can see that there is a point of connectivity (density is that idea that trees are touching or connected) is between 59% and 61%. The connective change is the key to lighting a majority or having a campaign that flames out.
Harold Katzmir from FAS research showed me this program.
