I just observed that the MAA has (long ago, actually (1986)) adopted approval voting.
I do not think I approve. I think that voting is about making a decision that you have to live with and the this feels like a typical 21-century feel-good way of avoiding making a decision. I read the Wikipedia article on the topic and found nothing there to change my mind.
I do concede that there are situations in which it might be acceptable, but certainly not in government elections.
