Continuous voting sounds like it might be an interesting use of a blockchain technology, especially the aspects about vote-delegation to a representative with the ability to override that transfer at will for specific votes.
Part of our country's fairly long history of democratic security has been that it takes a whole lot of effort for anything to get done, especially when that anything is passing laws. The fact that it's a fairly lengthy process to create or change a law means citizens and organizations can be comfortable in not being subject to wildly changing regulations. If something is to become illegal, or vice-versa, it's not likely to happen by surprise as long as you're paying attention. Continuous voting would potentially introduce quite a bit of instability, because the Government's actions would be too difficult to predict based on wildly changing public consensus.
This might be an interesting way to adapt the U.S. House of Representatives for a larger population and changing communications technologies. Constitutionally require all new laws to be passed with sunset clauses and re-voted every 4 years. Use more of a direct democracy in the House, where voting is out of the total population, but a Representative casts the votes of everyone who has delegated their votes to that individual. Let the Representatives be advocates and speech-makers and politicians, but let people themselves step in and cast their votes if they want, on a predictable schedule.
