In addition, good elections have a couple more properties. They should be understandable by the average voter. Paper ballots work well for this (esp. in FFTP jurisdictions). Online voting makes it really hard for even experts to completely understand the system, and impossible outside of a tiny number of experts to verify.

Second, elections are a social activity, and should feel like it. Anything that make an election feel like we’re all getting together to select our leadership, rather than an adversarial process should be encouraged. Online anything these days seems to be optimizing for max animosity. A counterexample might be the Australian democracy sausages.
