I agree with Google that advertisers will eventually sort themselves out. I have no objections at all to discreet banner ads, but irritating/puerile animations or anything which obscures the text I'm trying to read or forces me to click on a close button I find unacceptable. For the foreseeable future I'll continue to use Adblock/Ad-Art, but if advertising becomes more sensible and restrained I may have no need to use those.
