Whenever the results of a vote would not have substantial impacts on the people who did not, or could not vote, eligible voters are welcome to use whatever suits their fancy: e-voting, tossing dices, goat entrails… We won’t notice, so no problem. In all cases of really important voting instead, that is (at least) all political or administrative elections: here is why online/e-voting is something that you should just avoid, period.
This essay expands a proposal on Open Data in schools that I made in 2011, which requires very little, if any, funding and central authorization/coordination to be implemented. As of this writing, I know of no other proposal of the same kind, with the exception of this 2012 presentation from New Zealand. Also, I have not heard of any large scale implementation, or had occasion to do any real work on this topic. However, I am even more convinced now than in 2011 that the idea has a great potential.
