The Corporate Social Graph - some personal qualities?

Having taken a second look at the 'Social Map by Sean O'Driscoll', I believe he's provided some interesting indices for measuring the personal social graph:

In his diagram he uses the following qualities:

• Reach
• Density
• Speed
• Structural cohesion
• Proximity
• Personas

However, I wonder whether the properties he gives are also the same ones you would use for the Corporate Social Graph?

Note:
Following a conversation with Michael Myers, COO at Fresh Current, he has answered some questions on his opinion about the Corporate Social Graph. I will be posting his replies here as soon as possible.
