'George Bernard Shaw once complained of communism that "it takes too many evenings". The same is true of democracy in Switzerland - or Swiss commune-ism, if you will. It takes a lot of evenings.'
"Direct Democracy in Switzerland" by Gregory A Fossedal
One way to assuage this "too much effort" problem may be to facilitate voters involvement as and when they have the time and inclination: the Internet provides a 24/7 system for debating and voting. But what if you would still rather do something else? Perhaps the default setting for your vote could be to transfer it to your Member of Parliament or some other politician of your choosing.
