The online community is a democracy. Let's use blogging as an example. When we sign up to Google's blogger, we give up our natural internet sovereignty (could we not, in theory, create our own blogging platform and make our own rules?) and surrender it into the hands of the community, as Locke discussed in "Of Civil Government." So, online we have the same rights as any other individual online--we can read blogs and comment on them and even create our own blog as we choose (there are some exceptions, but they're insignificant).
How does this online democracy affect those in communistic nations? How does online democracy change their worldview? How do people living in exile (like the Tibetans in India) use virtual democracy to forward their cause?
