A very telling poll.

What is important is do web surfers use it? 15% to 25% is what I am reading.

I use Ghostery on one browser on one computer.
I can always allow the ads if I want to see what's up on a website.
I am more bothered about ad tracking.

Also, I test if my latest methods of getting our ads out there out-runs and evades ad blocking programs -- the sword cuts both ways ;)
