except that ads seem more poorly targeted than what they once were

It usually takes a while for ads to be properly targetted when first put on a page. However I agree that targetting isn't too hot but I usually find that down to misinterpretation of other keywords - (eg mention a location and you get swamped by otherwise off topic ads for business at that location). I know that there are ways of telling Adsense to ignore blocks of text but often "good" and "bad" keywords are mixed in the same sentence.
