I have noted that of the reading public it goes about this way...

Interested in entertainment: 99%

Interested in facts: 5-10%

Interested in self/development or, dare I say, enlightenment: 1/2 of 1 percent!

There is some overlap, of course...some like all of the above.

Given the general situation, though, it's not surprising that a casino or a really stupid action movie will attract 30 million people, while a spiritual centre will attract 35! ;-)
