Sure, let's commit some logical (statistical) and inferential fallacies here:
Increase in McDonalds burgers eaten is an indicator for the quality of the food
Pupularity has no necessary link with quality.
Here is what is more likely: Skepticism (an outrageously bad term for common sense) has originated from a group of very smart and educated people with strong academic backgrounds and/or high intelligence.
The lowring of the average standard that has occured *necessarely* through the increase in members of the movement makes it more accessible to the common person. And so we have moved from the thin upper tail in the Gaussian to the wider realms of the mediocraty. Hence more downloads.
If the SGU wants more listeners, they should lower the standard!
Just one way of seeing it! Probably wrong
