"Focus on the persona of your buyers rather than your product."
Think like a publisher...what will your buyers want to believe about you or your company? Don't talk about the product itself, nobody cares about your product. Bring the skills of a journalist to the task of discussing the interests of your buyers in the language they use.
1. Nobody cares about your product
2. No coercion is required
3. Lose control
4. Put down virtual roots
5. Create triggers that encourage people to share
6. Point the world to your doorstep
