"Developers of Adblock Plus, an award-winning add-on for Mozilla Firefox and Google Chrome boasting over 12,000,000 users, announced that starting from version 2.0 the extension would come with a white list of unobtrusive, privacy-respected ads. These will be allowed by default; users will still be able to block them by unchecking 'Allow non-intrusive advertising.' The developers say: 'Only 25% of the Adblock Plus users seem to be strictly against any advertising.' What is this — betrayal of ideals of annoyance-free web or birth of independent authority for standards for advertisement?"Ads are sometimes annoying, but they also make certain websites (like this one!) possible. Getting the balance right is tricky — I know I often avoid sites because of interstitial advertising, pop-ups, etc. Whitelisting sounds like a good way to reward sites that try to keep it subtle; offloading and generalizing the task of categorizing ads into annoying or acceptable gives sites and advertisers a good threshold to duck beneath. Next step I'd like to see: a sliding scale, so browsers can be set to zero, or eleven, for tolerable annoyance.
