Rangedriver I disagree. I think direct democracy is a poor choice of government. As I have said before, step outside of your academic circles and go ask the average Wal-Mart shopper what their opinion on politics is. This is your majority, not the Nick Szabos of the world.
The reason the founding fathers of America decided on a representative democracy isn't just due to technical limitations. The average cog-in-the-machine has no idea what is best for the majority, and doesn't have the inclination necessary to educate him or herself enough to form a valid opinion. They are easily swayed by social manipulation and hype. (take a look at the front page of Reddit and how corporations routinely astroturf content there)
The representatives were supposed to act as educated voters who helped alleviate the need for the common man to be abreast of every issue. They also were supposed to help ensure that if a painful decision needed to be made, it would be made even if it wasn't popular.
Again, you're referencing direct democracy as a concept established in context of the past.
All we're really talking about here is the science of ideas. If an idea is proven to be objectively stupid within the spotlight of the public arena, then its life as a workable idea will be short. If however it is a demonstrably good idea, then it will gain gravity.
Of course, it's true that you might have a population that is mostly comprised of imbeciles, which could be problematic, but that doesn't make the system imperfect.
The emphasis would be to suitably educate the population - an emphasis which has hitherto never been a priority, and has even been dangerous, as much of the power of the old world
relies on the maintenance of an ignorant population. Hence the somewhat retarded opinions of your average Walmart shopper.
It really comes down to two choices: The creation of a global hive-mind cellular super-brain based on freedom and technology... or intellectual apartheid.
I'd sooner take my chances with the thickies.
