Here's a pair of interesting Google videos.
The first one is a presentation from Google's "Uber Tech Lead for Search Quality and User Happiness" Dan Russell. Here's the abstract for it:
How well DO people search on Google? Although popular opinion is that "everyone is above average," that obviously can't be true. The truth is that self-perceptions of search expertise are often wildly over-estimated and that people, on average, actually use only a fraction of the potential of Google. They both don't know much of what's possible, and don't understand where internet search capabilities are headed. Since the rate of change and improvements isn't slowing down, in this talk I'll examine where we are, and where we're headed, and conclude with some heuristics for teaching research skills in the years ahead.
The video lasts about 36 minutes.
The second video comes from the Khan Academy, which Google's first employee (after co-founders Larry Page and Sergey Brin) just announced he was leaving Google for. Russell also appears in this video, which is much shorter, about searching for similar images:
