How many people work at Twitter?

Forty-five. Do you believe that? Just 45 people work at a company that’s grown from 1.6 million users one year ago to nearly 32 million today. In January, the company had only 21 employees. Thing is most of the 45 employees have little sales or business experience, according to the Wall Street Journal . The company’s founders told WSJ they hope to staff up to 90 people by year’s end.
