Somebody explain the Confessions votes to me. Genuinely. I want to understand.
Missing a few names that belong in the top ten, but the top three is basically right.
Wild that Confessions is winning this. Scroll down — the real answer is further down the board.
Came for the argument, stayed for the comparison grid. The numbers settle half the fights here.
Voted, but this order is going to look very different in a month once more people find it.
Confessions at the top is the correct call and I'll die on this hill.
