On Wednesday, November 6, Twitter, the so-called microblogging service, went public, in the private sense. Shares initially offered at $26 were by the end of the day trading near $45, giving a company with fewer than 900 employees a market value of more than $31 billion, and meaning that each of the service’s 230 million users—who are also, in a real sense, its producers—could be considered to be contributing $135 to the company’s value. That value is almost certain to fall, since Twitter shares appear ludicrously overpriced.
