LinkedIn vs Leadership Profiles

You know what’s fascinating?  Leadership Profiles have been around a long time in print form, and now on the web, but they’re hopelessly going to be out of date.  With an independent party trying to collect data, like this profile of one of my colleague Scott LaGanga, it will never be as accurate as his LinkedIn profile [See Scott LaGanga on LinkedIn].

I wonder how long until LinkedIn starts cutting vertical directories of their userbase and threatening businesses like Leadership Profiles?
