Nancy K. Humphries gets to the heart of the matter in this Huffington Post piece.
"Google often fails to serve people who search it or the people trying to get their sites noticed. All too often Google's results completely miss the mark....
Google will never equal the library in precision and accuracy because this company is too arrogant to even listen to a librarian. Google employees are young, so young they still believe that only they know how to do things.
I personally witnessed a speaker from Google tell members of The American Society of Indexers at a San Francisco conference that Google had gotten rid of the one librarian on staff in Palo Alto. She was a former cataloger; she was too "nitpicky.""
