Build With, Not For
When building technological solutions for a community, invite the community to participate actively in a manner of *co-creation* so as to ensure the right needs are being met. Build with the community, not for it.
Don't Preach To The Converted
Ensure that your service is useful to those who don't care about - or disagree with - your cause.
Don't create opportunities for users to publish information which an adversary might use to harm them.
Users Help Each Other
Give users ways to help each other so the community is self-supporting.
