Schelling Point... still :)

Bookmarklets | MOVABLE TYPE Found here

A Schelling point is a solution that people will tend to converge on in the absence of communication, because it seems natural or 'special' to them.

Ex.: You and a friend have to try to pick the same number from the following sequence:

2, 5, 9, 25, 69, 73, 82, 96, 100, 126, 150

Which number do you pick?
