According to The Register there are rumours that some of the big boys may even be about to do deals with Adblock. (I suppose Adblock has to have some means of making money.)
I'm sure someone will write Adblock Plus Plus to counter that.
However this is a good thing as getting the advertisers to pay a premium for access to my screen's real estate is beneficial to me, the web site owner, and even the advertiser. Otherwise these sites end up looking like some porn site with everyone scraping the bottom of the barrel.
