As long as it's not flashy, video, have sound, and kept lite I don't really mind ads... It's just when sites are basically hijacked by ads that I refuse turn off adblock (like youtube on every video)... When I turned off adblock I was rather suprised, just a couple banners and one side banner... I can't even hit the 1mb limit but I'll keep it off here just cause the effort was put in to make it as non obtrusive as possible...
