I have had this idea for a long time: An online realtime voting platform, where you can change your mind about policies at any time, and what the people want needs to be implemented. And of course all issues and policies must be put on the platform for people to vote on.
Of course initially we would have to learn, that changing our minds too often will lead to things not getting done at all. And it is doubtful, that a lot of people are even capable of becoming informed and reflecting beings, not to be swayed by a hip populist radical, and thus causing shit to happen. Also the sheer number of issues and policies would be so many, that most people couldn't make up their mind on everything. But that's OK, since people can raise awareness and simply vote later, when they became aware. Another issue would be what the choices are that people have on the platform. How to give all relevant opinions as choices? How to know what is relevant? Or can voters apply for adding a new opinion? But then who grants the right to add a choice? How to prevent spam?
So there certainly are huge issues with the idea. But maybe, over time, we would develop into politically reasonable societies and politicians would have to fear the opinion of the people, because one scandal uncovered, and they could end up kicked out tomorrow. Maybe it could also better designed, so that there is some minimum time between being able to change ones stance about something. Or some maximum of policies one can have an opinion about per day.
Even initially to have such a platform without real political consequences of voting, would be super interesting, because you could lookup what the current opinions of the people are.
