Dave Rendall published a manifesto at the ChangeThis site, and then reported in his blog the response that occurred around the world. We all know that blogs can spread messages, but this example just goes to show the importance of spreading your idea out and continuing to let it grow. However, wherever, and whatever you publish, keep it growing; keep telling people about it, and keep the idea exciting and alive.
Based on Dave's example, three things come to mind:
1. Get your idea published in other forums (ex. ChangeThis, magazines, newspapers, etc.).
2. Post about those other publications and your article there.
3. People like me will find out about it all and write about what was written, widening the footprint even further!
