Zynga Slashes Outlook, Shares Tumble (The Wall Street Journal) Zynga rattled Wall Street Thursday by cutting its financial outlook thanks to difficulty winning audiences for the social games company’s new titles, helping send its shares plummeting after hours.

Like airplanes. And bridges. And chairs.
