"I set up DIYDrones.com as a social network (on the Ning platform), not as a blog (so 2004!). That distinction—a site created as a community, not a one-man news and information site like a blog—turned out to make all the difference. Like all good social networks, every participant, not just the creator, has access to the full range of authoring tools: along with the usual commenting, they can compose their own blog posts, start discussions, upload videos and pictures, and create profile pages and send messages to one another. Community members can be made moderators, to encourage good behavior and discourage bad.
What this meant was that the site wasn’t just about me or my ideas. Instead, it was about anyone who chose to participate. And right from the start, that was almost everyone. The site was soon full of people trading ideas and reports of their own projects and research."
