@bb - if an app. does what it does effectively and bug-free, it won't need to be updated often. Install it, add the toggle script to your bookmarks for the rare case when it blocks something you want to see, then leave it alone. It just works.

The only ad blocker I've found that will block the video ads on Comedy Central.

It's unfortunately not updated too often. Also, for those that don't want to install something that requires administrative access, take a look at http://lxr.mozilla.org/mozilla/source/camino/resources/application/ad_blocking.css

the only ad blocking program you need, for every browser on your computer.

Anything like this should be built into OS X by default ;)
