of course -- I always knew this is so, and therefore am still laughing at attempts to "calculate" the income of some Casey Neistat merely be figuring out the value of their AdSense clicks. In light of those being in the $100,000s just imagine what these people really are making (from those little Amazon or GoPro or Manfrotto affiliate links they also use)...
Not that this is all tht important, maybe rather off-topic here.
Just saying though...
