I know that ignorance is actually great for online business (especially in my specialty, internet marketing...because it means more people will click on ads thinking they are search results).
But for some reason this video depresses me to no end. Maybe because at the end of the day, an ignorant public is actually terrible for everyone. For me it really hits home just how uninformed the general public is and how much harder it is to get people to respond to your products in the way you intended.
