I'm not sure about the whole internet idea as a way of applying egalitarianism to broader society. Sounds like it could potentially corrupt the process as opposed to make it work (happened with voting machines, why wouldn't it happen here?).

I have my doubts about whether 'utopia' will ever be possible. But I'm sure that better systems are possible, and there's nothing wrong about devising a better system than capitalism.
