I believe these steps are unprecedented in promoting understanding and enabling participation on the web. I hope you will take a look at these documents, read them carefully, and share your thoughts.
For me this another step in the evolution of the ideals of participation and transparency. And it's so interesting to see these type of social experiments being explored. I applaud Facebook for a) admitting they made a mistake and b) for taking the risk in opening up their policies and principles for open debate. You can bet this one development that'll be watching carefully. But for now, I'm off to review FB's proposed documents to see what I think.
