I had created a Linkedin.com account few years back and stopped in the middle wondering why I should be putting important information about me in a website like that. Well, for businesses it would be vital like ProFlower info on Linkedin.com, for example. The company has an online business and a Linked.com account would be very beneficial in marketing their service of sending flowers or bouquets.
But for an individual, I doubt if it would be more beneficial than delicate. Nowadays, one cannot be so sure. Even in social networks like Facebook, Friendster and Multiply, everybody has to be extra careful in giving out personal information like phone numbers and the like.
