Google And Their 10,000 Human Evaluators

As seen on Dare Obasanjo's article from Seattle's Scalability Conference held on the 6th of June, 2007, Google has 10,000 human evaluators, as told by Marissa Mayer when asked:

"How do they tell if they have bad results?

A: They have a bunch of watchdog services that track uptime for various servers to make sure a bad one isn't causing problems. In addition, they have 10,000 human evaluators who are always manually checking teh relevance of various results."

Over at Webmaster World, kamikaze Optimizer rationalizes:

"Yeah, I remember the past discussions and the leaked document, but 10,000 is a huge number.

Think of it this way – out of 10,000, 1% of them would be talking about it on blogs and the like…, and since the leaked document (what was that, 2-3 years ago?) we have heard nothing, correct?

I have seen Google IP's hit my sites (Corp IP's that is, not bots).

I blocked one by once for using a bad user agent and the employee emailed me, it was all very funny.

Odd and interesting, I think, about the 10,000 number.

It is clearly huge investment in quality control, if it is done correctly. "

Yes, the number was given as 10,000 but the massive total does not tell much on whether all the human evaluators are full time or part-time or even outsourced.
