In the past 10 years, many of the biggest publicly traded companies in the U.S. have been getting rid of staggered boards and dual-class stock structures. Currently, for example, only about 24 percent of S&P 500 companies have classified boards, down from 61 percent in 2002. But there hasn't been such a significant change among new arrivals. Of the 76 companies that went public last year, nearly 65 percent had classified boards. In 2002, 82 percent of IPOs had the feature. - Mitchell Tsai

Of the eight high-profile IPOs in the social networking and new media space last year, all either had classified boards or dual-class structures, with some having both. Of these companies, Zillow Inc (Z.O) and LinkedIn had both, Angie's List Inc (ANGI.O), Jive Software Inc (JIVE.O) and Pandora Media Inc (P.N) had classified boards, while Groupon, FriendFinder Networks Inc (FFN.O) and Zynga had dual-class structures. - Mitchell Tsai

Thanks... AAPL looks a bit high to me. - Mitchell Tsai

They are likely to see a bump when they announce the iPad 3 next month, I reckon. - The original Kevin

Other women in Silicon Valley have been role models. Many, like the Google executives Marissa Mayer and Susan Wojcicki, have quietly campaigned to promote women inside their companies. Others — like Meg Whitman, the former chief executive of eBay who now runs Hewlett-Packard; Carly Fiorina, the former H.P. chief; and Carol Bartz, the former head of Yahoo — have reached pinnacles of success in tech. - Mitchell Tsai

But none have made promoting women a cause the way Ms. Sandberg has. - Mitchell Tsai

EVEN so, some say her aim-high message is a bit out of tune. Everyone agrees she is wickedly smart. But she has also been lucky, and has had powerful mentors along the way. After Harvard and Harvard Business School, she quickly rose from a post as an economist at the World Bank to become the chief of staff for Lawrence H. Summers, then the Treasury secretary. After that, she jumped to Google and, in 2008, to Facebook. - Mitchell Tsai

There’s no denying that Ms. Sandberg has been remarkably successful at Facebook. When she joined the company, it had some 70 million users and no business model. With her in the C.O.O. seat, profits have reached $1 billion on $3.7 billion in revenue. - Mitchell Tsai

Soon it became clear to me that quietly and en masse, French parents were achieving outcomes that created a whole different atmosphere for family life. When American families visited our home, the parents usually spent much of the visit refereeing their kids' spats, helping their toddlers do laps around the kitchen island, or getting down on the floor to build Lego villages. - Mitchell Tsai

When French friends visited, by contrast, the grownups had coffee and the children played happily by themselves. - Mitchell Tsai

Middle-class French parents (I didn't follow the very rich or poor) have values that look familiar to me. They are zealous about talking to their kids, showing them nature and reading them lots of books. They take them to tennis lessons, painting classes and interactive science museums. - Mitchell Tsai

Yet the French have managed to be involved with their families without becoming obsessive. They assume that even good parents aren't at the constant service of their children, and that there is no need to feel guilty about this. "For me, the evenings are for the parents," one Parisian mother told me. "My daughter can be with us if she wants, but it's adult time." - Mitchell Tsai

French parents want their kids to be stimulated, but not all the time. While some American toddlers are getting Mandarin tutors and preliteracy training, French kids are—by design—toddling around by themselves. - Mitchell Tsai

One of the keys to this education is the simple act of learning how to wait. It is why the French babies I meet mostly sleep through the night from two or three months old. Their parents don't pick them up the second they start crying, allowing the babies to learn how to fall back asleep. It is also why French toddlers will sit happily at a restaurant. - Mitchell Tsai

Delphine said that she never set out specifically to teach her kids patience. But her family's daily rituals are an ongoing apprenticeship in how to delay gratification. - Mitchell Tsai
