Future Vision by Erwin Van Lun on this article
People who are involved in the groups in which they live and then specifically with the people they know. That’s why the who’s-who section in professional magazines are so widely read (do I know someone? Do I see a familiar photo?) This service takes this a step further and automatically selects the changes of people you know on a professional level. Furthermore it selects them in all branches because they’re your contacts. By joining the groups an individual works in a career coaching brand (which LinkedIn is becoming) will be able to guide the personal development of an individual much better.
