Social software is the experimental wing of political philsophy, a discipline that doesn't realize it has an experimental wing. We are literally encoding the principles of freedom of speech and freedom of expression in our tools. We need to have conversations about the explicit goals of what it is that we're supporting and what we are trying to do, because that conversation matters. Because we have short-term goals and the cliff-face of annoyance comes in quickly when we let users talk to each other. But we also need to get it right in the long term because society needs us to get it right.
