What Google is trying to find is pages where people write about a topic without knowing what the keyword density is. Everything they do tomorrow, next week, next month, and next year will be all scout trying to find pages that seem to cover a topic well rather than pages from SEO guys. They are building quite an a arsenal of heuristics. For example, did you know you'll rank better for "green" if you also mention red, blue, and purple? People writing about a topic naturally mention other related things. People focused in leyword density etc. don't.
