Craig Silverstein on Nigritude Ultramarine

Not really on nigritude, but a very good interview with Google emploee #1 Craig Silverstein. Here is an except:

Q: Some computer scientists suspect that PageRank is dead, because Internet marketers have managed to exploit it by creating false popularity for their sites...   Are there any other algorithm techniques that you are using that are playing a bigger role?

A: Well, there are certainly other techniques that we are using. Talking about it is the trickier part. In broad terms, techniques we use fall into, like, two or three categories, and one is we try to understand and leverage human intelligence. We look for signals that people put in to indicate intelligence, like deciding to link from one page to another or annotating text with the description of what the text is about.

I am not going to comment that a link was a heart of the original PageRank algorithm. What really interests me is when Google ranks pages on nigritude ultramarine [google.com] where the heck are they finding any signals of any intelligence?

He must be joking. Anyone thinks otherwise?
