Fax machines have helped, and anything
that facilitates the exchange of ideas will only make
China bend closer to a 'democracy standard'.
This network facilitates more propaganda; not the "exchange
of ideas". A Chineze citizen would have to be a naive idiot, or
a hard-core dissident not minding some time in a jail, to post
anything subversive over a state network.
If you see
how China has changed from 10 years ago to now (some form
of capitalism), you will see that they cannot and will not
run the country as communism was once run.
Capitalism != freedom of spech. Look at what's going on in Singapore.
