Art3x writes "When developing search engine technology, Microsoft focused on returning good results for popular queries but ignored the minor ones. 'It turned out the long tail was much more important,' said Bing's Yusuf Mehdi. 'One-third of queries that show up on Bing, it's the first time we've ever seen that query.' Yet the long tail is what makes most of Google's money. Microsoft is so far behind now that they won't crush Google, but they hope to live side by side, with Bing specializing in transactions like plane tickets, said Bing Director Stefan Weitz."
