Not surprising. With the advent of Siri and other knowledge-based technologies and mobile devices becoming smarter the writing is on the wall. In addition private and public apps and APIs are eating holes in traditional search channels.
Knowledge is easy for Google to collect on a basic level
Knowledge is easy to aggregate on a more advanced level. This has been the major directive in my opinion in the direction of G over the last 3 years

Where audience and knowledge meet is where the 'new search' and conversion zone will be for many businesses.
Search without context is slowly becoming meaningless.
