speaking of flash, i decided not to use adblock on Chrome.
I read a compelling argument against doing so a little while ago, which basically boiled down to, the small, non-intrusive ads help pay for the websites that i visit, so I should let them be, even if I never click on them, the site still get pageview credit for it and thusly get paid. however, the large, loud, bright Flash ads are pointless and annoying and should be blocked. and the loud bright flash ads are the ones that everyone really wants to block anyway.
so instead of using Adblock, I use Flashbock.
and so far, I haven't really had any issues with the ads that.
