No one in this thread have suggested to completely replace everything with direct voting

  the only way to improve situation is adding some elements of direct voting that would improve efficiency of communication between people and the government.

1) What are a good set of rules for the system.

2) If the existing system can no longer self-correct, how can one implement a good set of rules.

'Direct vote' might address the second issue. It's not the only way, but it's better than a violent revolution.

I'm not opposed to all direct voting, but it does have inherent problems. The most obvious is that the world is far too complicated for a majority of citizens to research all the issues that affect them. In a well-functioning representative democracy, a politician would have the resources and time to understand the issues. Granted, that seldom is the case in reality.
