The problem of coordination
From Deliberative Democracy Institiute Wiki
As the group getting bigger, the number of connections between members of group getting bigger. This cause slowing down of the process of coordination. If the group will use peer-to-peer equal terms deliberation, the amount of communication time will get bigger exponentially' thus sending the group to an holt. To solve this, groups usually use un-equal methods of deliberation and influence.
The mathematical formula for the number of connection lines in a group is:
cl=((n-1)^2-(n-1))/2
cl = connection lines; n = number of group members
In large numbers we can round up the equation to:
cl=(n^2)/2)
