Personally, this could be a real problem, if Ad services decide to pry open the doors on our ability to deny them our screen real estate. I block Ads, primarily due to the fact that I don't want my web surfing history and behaviors captured by some uncontrollable mob a ad-servers. Further, most advertisements are akin to the dreaded <flash> tag of old! animated, ugly, and obtrusive.

We are coming to a point in the Internets genesis, where technology should evolve to allow the "information consumer" to directly reward the "information producer"... without the need of an intermediary like Google Adwords, etc. etc.
