VisiblePath.com - Business Social Networking with a Twist

Visible Path is a unique business social networking option that automatically maps social relationships and helps you to find and connect with mutual friends. The service is different because it uses networking algorithms to rate relationship strength and contact strength based on calendar events that involve that contact and how many times you´ve emailed them. This is a great way to network outside of your immediate circle of contacts, and who knows, you might even be within six degrees of Kevin Bacon! They operate on an Outlook plugin, and the company is currently working on features which track relationship strength based on phone calls and instant messaging.

"Visible Path helps you manage your professional social network and build the relationship capital you need to succeed.

Will they extend their service to track other emails you write from other providers such as gmail? Is the functionality a bit trifling? Don´t you already know who your most important contacts are without Visual Path dictating it?
