Google just announced the completion of the long awaited Caffeine in Our new search index: Caffeine
“Caffeine provides 50 percent fresher results for web searches than our last index, and it’s the largest collection of web content we’ve offered”
With an emphasis on freshness there’s a slight chance that the number of “tricks”, “secrets” or “loopholes” revealed in “secret reports” and overhyped products will go down because there’s no need to do anything special to get indexed.
