CNET News.com: "Publishers who have seen a bump in revenue through Google's advertising program are heaping praise on recent changes, while some advertisers complain of increased costs.

Google's policy statement says the change allows advertisers to resurrect keywords that previously had been disabled because of low click-through performance. "
