As for the point of this site, I defer to Alain de Botton:
"Curiosity might be pictured as being made up of chains of small questions extending outwards, sometimes over huge distances, from a central hub composed of a few blunt, large questions. In childhood, we ask, 'Why is there good and evil?' 'How does nature work?' 'Why am I me?' If circumstances and temperament allow, we then build on these questions during adulthood, our curiosity encompassing more and more of the world until at some point we may reach that elusive stage where we are bored by nothing."

Or, as Zippy the Pinhead puts it, frivolity is a stern taskmaster.
