Thanks - I noticed one comment from Matt early on:

Those links are links generated because of the sheer quality of your business or the value add proposition that you have that’s unique about your business. Those are the things that no one else can get, because no one else has them or offers the exact same thing that your business offers.

In general it sounds like Google is aiming for a relatively complex taxonomy of link types and weighting for them.
