It was going to be really important to have a single click, not multiple clicks (i.e. any two-separate-votes system was going to have people overwhelmingly just using one of the votes and largely ignoring the second one)
I feel like it’s slightly less work for me to consider one axis and up/downvote it, and then consider the second axis and up/downvote it, than it’d be to vote on two axes with a single click. The former lets me consider the two separately, “make one decision and then forget about it”, whereas the latter requires me to think about both at the same time. That means that I’m (slightly) more likely to cast two votes on a multiple-click system than on a single-click system.
Though I do also consider it a feature if the system allows me to only cast one vote rather than forcing me to do both. E.g. in situations where I want to upvote a domain expert’s comment giving an explanation about a domain that I’m not familiar with, so don’t feel qualified to cast a vote on its truth even though I want to indicate that I appreciate having the explanation.
