Google CEO Eric Schmidt reportedly attended Wall Street Journal’s “All Things Digital” conference wearing a T-Shirt that read “quiet period” on the front and “can’t answer questions” on the back. This follows the controversy surrounding the interview given by Marc Benioff, CEO of Salesforce.com (another company that has filed for an IPO), to the New York Times. “Perhaps Marc Benioff should have had a similar t-shirt made up . . . and then stuffed in his mouth,” says David Hornik, a venture capitalist with August Capital.
