I really hate the format of arguments/debates in person. I feel like they would be a lot more rational if done through email or something, where one isn't expected to respond immediately as part of a conversation. I'd like a website which facilitated debates, allowed debaters to branch off multiple threads of debate and close threads once they are settled (ideally until all threads are closed), backreference other threads, citation lists that get automatically aggregated, etc.
