If Silicon Valley is just one big high school, as investors there have been known to point out, then the most popular kid in class has long been Facebook. In recent years, as Mark Zuckerberg’s company strode toward an historic IPO, smaller social networks like LinkedIn came to look like scrawny nerds at the back of the cafeteria.
Turns out that social orders are fragile things. Facebook’s offering has fizzled, with shares falling 30 percent to a low of around $26. Lowly LinkedIn, meanwhile, is trading in the mid-$90 range—up nearly 50 percent since January.
