1.  The anonymity makes users have more humanity, or less?The anonymity is hiding, encourage users to express more of their honest thought. But, express things with hiding doesn’t have responsibility. Then, can justice exist without responsibility?
2. Does cultures like Anonymous(or gathering place) only exist on web? What other “a single point” in space can be?
3. Is the internet gathering culture more of individual thing? Or collectivity? Who leads the culture, or movement?
