  Since the publication of Malcolm Gladwell's book, hunting
                         tipping points has become a popular hobby in the press.
                         However, not all apparent tipping points are real, often the

                         turning points in an S-curve can be mistaken for a tipping point
                         when, in reality, they are an artifact of the curve itself.


                        There are two kinds of tipping point.


                         A direct tip where the change occurs in the variable itself;

                         example, a respected investor sells his/her holdings in a
                         company triggering others to dump the stock.


                         The second is a contextual tip, where a change in some other
                         variable so changes the context that the variable of interest shifts.

                         Example, the Treasury Secretary comments that an interest rate
                         rise is likely; the next day there is a sell-off in the bond market.
                         The Secretary did not buy or sell bonds or even make a

                         recommendation but the context was changed.

                         Both direct and contextual tips may be deliberate, the result of a
                         manipulative action. Such manipulations may be legal in the

                         normal course of business, others may be illegal or immoral
                         designed to induce panic for profit.


                        Initial tips: These are tips at the start of diffusion. When the

                         diffusion of Facebook through the population occurred, it
                         described the expected S-shape with the upswing in the adoption
                         curve occurring about 2007: an apparent tipping point. But,
                         further research could not discover any reason behind the

                         upswing other than the normal operating of diffusion, a
                         graphical phenomenon.


                         However, it could be argued that there was indeed a tipping
                         point for Facebook but that it occurred much earlier. The real
