So obviously you have to make it as braindead simple to vote as we have made everything else. What I do not see the purpose in, is complaining about or nay-saying these attempts. You're never going to convince someone that one vote is worth more than it is, which is what people really mean when they talk about 'engagement', because your vote on its own really just doesn't matter much and people intuitively get that.
Reducing the cost of voting to match the actual value of a single vote is the best move we have IMO.
