Why Web Designers Should Not Use Ad Blockers

As an advertiser, I wouldn't even begin to consider advertising on Smashing's blogs. There are ten items (if you include their book, twitter, and Facebook plugs) on that page competing for my attention before I get to any content. The task-focus for someone viewing that page is to find the content. It's a horrible game to foist upon your readership.
If anyone is clicking those ads, it's either by accident, or because they're thinking to themselves, "Ok, obviously Smashing is hard up here, otherwise there wouldn't be 7 ads and 3 plugs."
The only reason why web designers should not use ad blockers, that I can think of, is to see how others are placing ads and learn from them, so when you have to design a page that has ads, you know how or how not to do it.
