What are the sustainable sources of competitive advantages for communities?

In the CollabFund blog, Morgan touches on some interesting concepts.

The only truly sustainable sources of competitive advantage I know of are:

  • Learn faster than your competition.
  • Empathize with customers more than your competition.
  • Communicate more effectively than your competition.
  • Be willing to fail more than your competition.
  • Wait longer than your competition.

However, when we take community into consideration, I feel we can expand on this list of competitive advantage.

The one that really springs to my mind is having depth of community knowledge (which also includes depth of relationships/connections as that is often required to get to the depth of knowledge).

Thoughts on adding this as a competitive advantage?
Is there something else worth adding to the list?
