An article at Wiredhas a ton of details about how Google’s search algorithms, index, crawlers and so on evolved over the years. I highlighted many of the points in my Search Engine Land write up on it.

A WebmasterWorld thread quotes a piece on the Google Caffeine index, asking if that means it is live.

One webmaster asked, “Does this mean that Caffeine is now live:)?”

We thought it was live dozens of times, but nothing really has changed since then. I fully believe that when it goes live beyond one data center, Google will let us know. I just don’t think that the quote above can fully mean it is live. I believe Search Engine Land will post a statement from Google on this topic later today – but as far as I know, it is not live.

Meanwhile, reading the Wired piece is both fun and educational.
