Thinking of Deleting My LinkedIn Profile, Convince Me Otherwise

I’m sorry, I just don’t get.  I’m sure it’s me and I’m just not making the most of LinkedIn, but before I spend any time and energy on a social networking site, I’ve gotta get something back from it, anything!

The whole LinkedIn thing seems like a colossal waste of time.  Aside from some creepy people from my past, no one of value has reached out to me in over three years of having a profile.  It’s here btw:  http://www.linkedin.com/in/joshuamorganbrown

Here’s what LinkedIn offers as their latest stats:

• LinkedIn has over 75 million members in over 200 countries.
• A new member joins LinkedIn approximately every second, and about half of our members are outside the U.S.
• Executives from all Fortune 500 companies are LinkedIn members.

I don’t know.  I’m thinking of getting rid of it entirely…where am I wrong?  Thoughts?
