In a phone interview with The Register, Peter Blum, VP product management at Instart Logic, said there's a battle going on between "quality publishers like The Register" and people who block ads.
Its not Usually the QUALITY publishers.. but its the hundreds of others that push things that
ONE: I don't care about
TWO: are Obnoxious
THREE: Take up so much screen its just a pain
FOUR: take up loading time with dozens of ads and scripts
so the more I can block the better.. I do white list some sites as they earned my gratitude for publishing good content.
