For strategicly thinking folks it is sometimes hard to understand how slowly things change, or how a strategicly correct idea has to "fight" against reluctance during years or even decades (example: "population grows & oil reserves stay the same > petrol prices go up > demand for smaller cars grows & demand for bigger cars decreases > be able to offer smaller, lighter cars and cars who work with other energies now!" vs. "the German automobile industry & the German gouvernment")

How wonderful to see that some things seem to change faster!  2007 17% of a set of 500 US companies used wikis; 2008 it was allready 27%.
