Twitter is going to have to go public at some point anyway, so it should be sooner rather than later. There's a point of view now in Silicon Valley that Wall Street is an evil and short-term-focused place and so private companies should take as long as possible before finally accepting SEC rules that require them to IPO. I disagree with this view. To me, going public is like becoming a parent: No amount of books you read before the fact teaches you how to do it. You learn how to be a parent by doing it, trial by fire style. Of course, you make mistakes but you learn how to cope and deal with the increased stress and time demands. As you get more and more kids, you become better and better at managing stress.
