LinkedIn recently added a revamped "Who's Viewed Your Profile" feature to its extensive list of upgrades for the professional social network. The site is hoping to encourage its users to engage more with the site by appealing to human curiosity. People want to know who is covertly examining their LinkedIn information, whether that person is a potential employer, current coworker, or personal acquaintance. Now, LinkedIn has provided its users with the means to reach out to the people viewing their profiles, hopefully expanding their networks and building beneficial relationships that can positively impact their careers. This, folks, is the beauty of social networking.
