     Children are a secret weapon for making investment decisions. In a nod to the wisdom of

youth, many wealthy and well-educated technology investors are seeking advice and investment

tips from their children, summer interns(实习生) and twenty something receptionists.

     Unlike the formal consumer tests that focus groups at large companies, these inquiries are taking

place closer to home, with friends and family. But their impact can be broad, because investors not

only help promote the development of new ideas but also invest billions of dollars in those ideas on

behalf of investment groups and wealthy individuals.

     These investors say there is a good reason to ask young people to help them assess new technology:

as the investors themselves are aging, the technology ----including social networking websites and

mobile gadgets- is designed for, used by and sometimes built by people half their age.

     And the trend may indicate the rise of something new in the venture capital industry itself. The

investors said asking the younger people for advice would have been unheard of in the dot-boom of

the 1990s. Then, investors were engaged themselves in the very technology they were financing, ordering

books on Amazon, downloading music from Napster and buying and selling on eBay. But now, in the

so-called Web 2.0 era, investors' personal interests have strayed away from new innovation: websites

like Myspace intended to connect people, free Internet calling tools like Skype or software for mobile

phones.

     And people now in junior school and high school have spent their lives with technology. " This is the

first generation for whom the computer is a native language," said Jim Gauer, managing director of

Palomar Ventures, a Los Angeles firm. " We are all going to have to get re-educated and learn that

language."

     Or they can do what Palomar have done: hire a native speaker . Last summer, the firm had an

intern, Adam Gottesfeld, 21, who was heading into his senior year at Princeton. Mr Gottesfeld so

impressed the firm with his technological knowledge that it has offered him a job as an associate when

he graduates.
