VisiblePath a successor to LinkedIn?

I’ve been on LinkedIn for a while.  My use of it waxes and wanes.  Why?  Because I don’t find it terribly useful.  I haven’t gotten a job through it.  I haven’t found an employee through it.  Really, I send and accept requests to/from my friends out of politeness than feeling like it’s going to help me in some way, shaped, or form.  Next week at Web 2.0 Expo, VisiblePath is “officially” launching.  Techcrunch (of course) got an early look:

Silicon Valley-based VisiblePath is a lot like LinkedIn, but it automatically determines who your real network is, and how strong each individual relationship is, based on your emails and calendar items that involve them. VisiblePath will officially launch next week at the Web 2.0 Expo.

Will I be checking this out?  Sure.  I’d like to see if it takes networking to useful point.  Twitter, blogging, and other ways of connecting have really worked for me in the past.  But being the geeky guy that I am, I’m willing to try it.
