A quick word of advice if you’re trying to explain the value and concept of community.
Show them, don’t tell them.
Show them another, similar community. Highlight how it works. Highlight the value they get from it. Highlight what will be different about yours.
It seems obvious – but then you might be surprised. It’s hard to grasp a community until people have seen it.
Better yet, show communities at all stages of the lifecycle. What it will look like when it launches, what it looks like at maturity, and beyond.
