If a better mobile experience was one of the drivers of the change I can see that, but the problem with responsive design is that it often sacrifices a superior design tailored For desktop or mobile in favor of a mediocre compromise that does neither especially well. Here mobile is improved at the desktop expense. The argument has already been made that given the average user age and current viewing preferences that desktop is the primary UI preference. It's a compelling argument that cannot be ignored. Given how much commerce that takes place that involve hi Rez scans - the taking and viewing of such images really favor desktop and tablets. If you want a good mobile experience, make an actual mobile app, or don't, but don't downgrade the UI for desktop without a solid business case. Maybe there is one, maybe there isn't. In defense of the old farts on here that solidly hate the new boards, if they got the money and numbers, their point is valid. As for us Gen X'ers - we built the internet and will be the first to call wildly_fanciful_statement on millennial presumptions.
