IMHO Yahoo's biggest mistake was never grokking search. And they had two opportunities. First: When Larry and Sergei wanted to sell their search engine to them for a few millions, in the late 90s. They said they are focused on curated content, which was the future they apparently believed in. (Just paraphrasing from memory, the stories read in various articles and books on Google & search). But I also wonder, even if Yahoo had bought them out then, would the world be different today. Perhaps, the inevitable future of search would have been just a bit delayed. May be evolved like social networks. Second: Killing their own search engine in early 2000s, when they had some 30% search share. That was after they tried using Google's search API. Then they started to use Bing. I clearly remember that although Google was the best, but one knew people (lazy friends) who would use Yahoo search. DDG has shown, there is always a market. edit: typo
