> Google won by making Google a destination in every web browser, and Facebook is winning by making Facebook the destination on everyone's phone. This is not true - Google won by being associated in people's minds with "I want more information about XYZ". Facebook won by being associated with "I want to see what my friends and family have been up to". > And the desktop browsing experience is fading and fading. Google has a very strong grip on mobile. They own Android, they own the most popular browser on iOS [1] and their margins are so big that they can outbid competitors to be the default search engine for the second most popular browser. > One has to consider the question, what would the marginal cost of adding quality search to Facebook's infrastructure be? And what sort of margins would their search product need to return to support that? It would probably cost Facebook as much as it cost Microsoft, and the return on investment would probably be similar - ie. not great.
