WALL STREET JOURNAL -- Jan 31 -- Sites like Friendster.com let users meet new people through their friends on the network -- in effect, a mutual friend provides an introduction. As the popularity of these sites has boomed, more people have realized that online networking can also be useful for business purposes. Making new business contacts is the third-most-popular feature of online networks -- after contacting friends and looking for jobs -- says Nate Elliott, an analyst at Jupiter Research, a unit of Jupitermedia Corp. of Darien, Conn. A total of 15% of all online users are interested in using networks to make business contacts.
Mark Brooks: I highly recommend the business network leaders LinkedIn.com and Ryze.com. OnlineBusinessNetworks.com is good guide.
