This may have nothing to do with anything, but where did the Google ads go? I liked how they prompted me to buy skipping ropes while I was skipping the boost ball. :D
Personally, I've never seen quite what the big deal is for ordinary, non-spastic banner ads... plus full adblockers tend to screw up websites with a small but significant frequency.
I wouldn't feel right blocking all ads. Popups yes -- Opera handles that nicely for me -- but generally if a site has ads, it needs the money it makes from them. The company knows how many times its ad has been downloaded, so if you don't at least let the ad load, you're not helping the site.
(Some people go farther and say if you support a site, you should click on an ad once in a while, but that part I don't agree with. Clicking an ad that doesn't interest you defeats its purpose.)
