suraj.sun alerts us to an anonymous-source story up at the NY Post, not what we would normally consider a leading source of tech news, claiming that Microsoft's introduction of Bing has alarmed Google. "...co-founder Sergey Brin is so rattled by the launch of Microsoft's rival search engine that he has assembled a team of top engineers to work on urgent upgrades to his Web service, The Post has learned. Brin, according to sources..., is himself leading the team of search-engine specialists in an effort to determine how Bing's crucial search algorithm differs from that used by [Google]. 'New search engines have come and gone in the past 10 years, but Bing seems to be of particular interest to Sergey,' said one insider, who spoke on the condition of anonymity. The move by Brin is unusual, as it is rare these days for the Google founders to have such hands-on involvement in day-to-day operations at the company, the source added." CNet's coverage of the rumor begins with the NY Post and adds in Search Engine Land's speculation on what the world of search would look like if Yahoo exited the field.
