"If you don't like the new design, for the time being you can click on the opt-out link at the bottom of the homepage – and bam, you're free."
Done.
I took a look at it when it was opt-in. The comments in the discussion were overwhelmingly against. IIRC they even said it made the mobile version worse so there goes the main reason for the change. But no, someone ?marketing, decides to go ahead anyway.
If I'd realised it was a WIP I'd have gone back and complained given feedback again. I guess that was the reaction of all the rest who didn't like it and when the feedback stopped you thought it was because we now approved.
