Microsoft CEO Steve Ballmer didn't really know how to answer. Can Bing be No. 1 in the U.S. search market?
"There's no good answer to this question," Ballmer said Tuesday at the Search Marketing Expo in Santa Clara, Calif. "If you say yes, you sound arrogant. If you say no, you sound like you're happy with second place. No one aims to be second, so the answer is yes."
