I deliberately, and almost ruthlessly enough, limit my LinkedIn connections to people I've worked with closely enough to evaluate each other. I really want it to be a career resource. The set of endorsements under the system as currently implemented, bears little correspondence with what those people would say about me if you asked them. This makes the data, and LinkedIn itself, less useful.
