There are so many ways to reach out from your own "community comfort zone" and impact other communities. Often there are sub-communities inside your larger one. Being able to create a Community of Opportunity - allowing everyone to create change and impact the community in their own way - is what I get from this article.
This is where you see a lot of Open Source projects navigating to. The smarter companies are seeing that, too. Letting your customers/community members tell you what they like rather than you telling them what they should like.
Great article - thanks!
