That's a very interesting article. I wonder whether search, in general (as measured by traffic on the major search engines) is declining, or whether people are using more specialized search websites/apps (this was kind of touched up in the article).

For example, when i have programming questions, my first place to look is StackOverflow as opposed to Google. or for restaurants I look at Yelp or Urbanspoon.

In other words, is search traffic just becoming more fragmented across different sites (Yelp, Amazon, StackOverflow, etc.) and apps?
