" Since then, most of Google’s successful products have been based on strong technical insights, while most of the less successful ones lacked them. AdWords, the Google ads engine that generates most of the company’s revenue, was based on the insight that ads could be ranked and placed on a page based on their value as information to users, rather than just by who was willing to pay more.63 Google News, the site that aggregates news headlines from thousands of media outlets, was based on the insight that we could algorithmically group stories by topic, not source. Chrome, Google’s open-source browser, was founded on the insight that as websites grew more complex and powerful, browsers needed to be reengineered for speed. Pick an innovative, successful Google product, and you are likely to find at least one significant technical insight behind it, the sort of idea that could have appeared in a technical journal. "
