Re: AdBlock
Unfortunately, some of my favorite websites - including The Register - are financed mainly by the ads they allow to be shown on their pages. Or at least, I am told they are there if you don't use an adblocker. (Actually, I have seen them when I very occasional visit on my iPad.)
It must make ad rate-negotiation quite interesting. The Reg: "Our visitors are responsible for $10,000+ of IT product purchasing per year, so pay us more." Advertiser: "Yeah, but most of them use adblockers, so charge us less."
It would be nice if the advertisers could be trusted not to do bad things, but since they are in the business of telling lies for money, that's hardly going to happen, is it?
