I’m using it in a slightly different way, not really coming from a corporate background myself.

As someone who focuses primarily on assisting online entrepreneurs rather than corporate people, I’ve recently seen the need to add LinkedIn to the social networks I use. After all, as more and more would-be entrepreneurs from the corp sector see the economic opportunities online, they still need to find someone like me on that kind of network to feel like it’s a “legitimate” connection. Somehow, the LinkedIn profile resonates better than my facebook and other profiles.
It’s amazing how these networks show the need for meeting and connecting with people “on their turf” rather than expecting everyone to show up on yours.
