I think it is silly to expect people to police themselves whether online or offline. Just like the real world, even the cyber-world needs regulation (by government) to ensure law and order in a society. One just needs to make sure the restrictions imposed are reasonable. I think Qatar does a reasonable job in this regard. While I disagree with what China does, I also disagree with a lot of their other forms of regulation. There is no reason to regard Internet regulation as different from any other form of government regulation; if you want to tell a government how to regulate (or not regulate) the internet you may as well go ahead and tell them how to run their country.
