I just ran across some research I did in December 2008, while working on the 10th Anniversary edition of The Cluetrain Manifesto:
- Google Book Search results for cluetrain — 666
- Google Book Search results for markets are conversations — 2610
- Google Web Search results for cluetrain — 394,000
- Results for Web searches for markets are conversations — 626,000
 Increasing at more than one per day. The numbers were 647 on November 15, 2008 and 666 on December 1, 2008. Results passed 600 on September 30, 2008.
Here are the results today:
I added two more, with quotes, because I’m not sure if I used quotes the first time or not, for that phrase. I would like to have the exact URLs for the earlier searches too, but I don’t. To get useful, non-crufty URLs this time, I needed to fire up a virgin browser and scrape out everything not tied to the search itself (e.g. the browser name, prior searches, other context-related jive irrelevant to this post).
Of course, Google guesses about most of this stuff. (Though possibly not for the first item: a word in a book). Not sure how much any of it matters. I just thought it was interesting to share before I wander off and forget where I found these few bits of sort-of-historical data.
