There are growing (nine as I write) significant attributes that will affect your influence. The issue is interruption of words...

Authority

What authority have you been given by you social graph and what authority can you command (depth)

Credibility

How credible are you on the topic in question, the closeness to your are of given authority

Expertise

Proven domain expertise from an independent third party that shows more than common knowledge or willing to stand up and be counted.  Think how others whom you are influenced by rate you

Location

Often overlooked but sometime meeting people helps or having someone local is a positive.

Proximity

Both the relationships between people and how they are connected. Closeness is more than family

Reach

Think about the size and potency of your "social graph"

Reputation

How others whom you influence rate you

Relevancy

The relevancy to local and disparate communities

Trust

Is like your bank account it goes up and down.  Trust is not fixed and varies by country and culture.  It is a mashup of many factors but also needs to be measured as a unique.
