Wikipedia is not to blame any more than MTV is to blame for Jersey Shore - they are both simply catering content that reflects how their audience wants to expend attention.

Looking at the numbers for perez hilton, farmville, facebook, television, porn, etc - paints a picture that the average mass consumer does not consider scientific knowledge to be notable.. or the inventors of this knowledge.

I blame Edward Bernays. Watch the BBC documentary 'The Century of Self' which provides a historical context for why the amygdala of the typical consumer suckles all the attention, while the neo-cortex sits waiting like the runt of the litter with only a vague notion of scientific knowledge present in daily life.
