I could see some small western European country like Denmark, students at an American university, a small town council, or even a liberal school district, full of cell phone-loving PTA moms eventually developing an app to have issues and proposed bills voted on by everyone using their Iphone and laptop. Once it starts the rest of the democratic world would follow. All potential issues and bills would be available to review. People cold advertise their issues online all they wanted. It would require an online petition to be brought to a vote. Not every one would want to read everything involved n the petition phase. Special Interest groups would do their best to bring forth their wants at this time, but requiring a fairly large percent of the population signatures on the petition could help weed out kooks, big-wigs and special interest groups. Once it was to be put to a vote, all information on the final proposition would be available for a period of time for people to read. They could vote at their convenience and vote on all items at one time, a warning could tell them if they missed an item to vote on. Security is only an issue if you let it be. PIN numbers, facial recognition software, and a plethora of other security is currently available. Many places still don't even require picture ID currently to vote. If you trust the internet enough to use a credit card online or file your taxes, I'm sure people would trust the system enough to vote online. They trust the world enough to not vote in the current system.
Direct democracy relies on a % vote from the population, not wait for total votes to arrive. So if your informed enough to vote on something you will, only negative to this idea is that people that don't care will vote due to peer pressure or media provocation etc. Instead of corporations needing to lobby several to a dozen politicians they need 1 simple ad campaign during white trash television. Has the potential to do very well or very badly depending on how its implemented, and the sooner the public gets used to their new responsibilities the better.
Thanks to technology and the Internet, votes can be registered almost instantly. We can move to a more direct form of government, but only if there are two important factors. Voter participation is one, followed by a standard system for verifying that each person voted once on each issue. There would have to be some kind of minimum quorum for votes to count and a way to prevent fraud so there are no snafus in the direct voting process. It would take a lot to move towards direct voting, but it is possible in the long run. One good place to start is to reform the Electoral College and have a direct election of the president of the United States.
And I have a group of underpaid college students lurking forums to make favorable comments about me for every bit of information that has to do with me. They will appear to be regular folks.
If anything the anonymity would allow people to get away with even worse hijinks. Lock down records? You got it. Block an entire network for disagreeing with you? It'll be done in a few minutes.
At least print media leaves records.
The advent of the Internet does not remove the impediments to direct Democracy. Normal people do not have the time or desire to be involved in the daily activities of the government. We hire and select people for this job. They are experts at governing, and it is their profession. Most people don't have the expertise for being a part of the government.
