I'm really on the fence about adblock. I never used it until youtube started having ads with volume that would pop out of nowhere. That got really loving annoying really quick. I never take the time to disable it for other sites unless I need to do it to see content. But I've never sympathized with those that bitched and moaned about websites having ads. I've kind of been hoping that eventually websites are able to get around adblocker.
Most of the ads I've seen online are pretty stuffty, and I can't imagine an intellegent person actually being influenced by them.
The video commercials on youtube are a different story, but I think the world would be better off without "check out this diet drug the government doesnt want you to know about" and "enter your credit card number to see if your idenity has been stolen".
Besides, having to depend on ads to make money just seems scummy.
