A post on slashdot suggested using http://freak.aagh.net/code/user.css as your user stylesheet (an option in browsers such as galeon/mozilla and opera, probably others). Basically it just looks for banners of a certain size, and doesn't display them. Under galeon you get a bit of a jerk as the banner is removed, but it's still a cool idea, similar to bannerblind for mozilla.
while this is a cool idea for some of the larger news sites, I wouldn't want it for smaller sites like uf. Most websites need to make $$ to survive and when I've got nothing else to do, I'll click through some uf ads just to help. If I had bannerblind, do I still get that opportunity?
Most of the time my mind blocks out the banner ads... it's the big ads that are half way down an article that annoy me...
At one point I wrote an http proxy server (using mod_perl) that replaced images matching certain expressions with a white image. Hmmm... I wonder if anybody has written a background thread, so that the banner ad gets hidden, but another procesds automatically retrieves the page that the ad is linked too... It's cheating, but the banner ad ppl will have no idea :-)
