It never ceases to amaze me how many people are walking around with computers, of one type or another, in one size or other, who aren't aware of some basic things.
Which leads me to this question that's relevant to AdSense. How many people out there are aware of an adblocker, how to get one and how to use it?
Forget those who just bought or downloaded the latest version of whatever that will block ads. How often do you talk with someone in ordinary daily life where the subject of adblockers comes up in the conversation?
