Wall Street Journal discovers TwitterThe Wall Street Journal is running a strange article about Twitter. Everything about it strikes me as bizarre, right down to the picture, which shows Jack Dorsey, the cofounder recently ousted as the company's CEO. Indeed, the article is more telling in what it doesn't cover than what it does.For example, it doesn't even allude to the company's office drama; cofounder Biz Stone subs in as spokesman for new CEO Ev Williams. It also skips over Twitter's latest privacy violation, which even affected the author of the piece. But it does, in a roundabout way, get at the heart of Twitter's problem: The tool for posting short text updates can be useful for businesses — just not Twitter itself. Cofounder Biz Stone suggests the company may find a way to charge business customers for "premium services." A great idea. If only it had tried it a year ago, before the market crisis made such a move look desperate, rather than a bold experiment. (Photo by Getty Images)
