There's nothing saying that these "decisions" weren't already made in advance.
Sure, but since any of them could be easily implemented in the show (and the voting cutoff was far enough ahead of the tape date that they'd have time to do so), I'd like to be more trusting.
My Luddite self figured out how to view the direct replies to a tweet, so assuming that's how they differentiated between the two #TPIR35K options, it's easy enough to count. And since fewer than 20 people voted on each question (except for Look of the Week, which received 30 votes), I just tallied the results myself, which will make it easy to tell whether the voting was legitimate.
(It turns out that shooting the first closed captioning bumper in the control room was the only unanimous decision.)
