1492:
The mods gave us a heads up more than a year ago, and they've gone to great lengths to: (a) explain why the changes were necessary, (b) give everyone ample time to test drive the new site, and (c) allow us the opportunity to offer feedback.
The first I heard about this was a month ago, long past too late to make any recommendations or bring up any structural issues. Sure, I recall talk about a mobile site, or something similar, years ago but that has been going on for years with nary a peep as to what was planned and never anything about an actual imminent change until November. SO I would disagree with your characterization.
I get that anything new will have good and bad, things people like and dislike, and there is always resistance to something new. However, having grown up when coding HTML was a thing, site designers seem to long ago have forgot the golden rules of site design. The first of which is the value of real estate. What shows up on your screen when you open a site is Prime and shouldn't be wasted. One of the best things about the original site was being able to see everything on one screen (especially on PC). That is now gone and I need to scroll to see everything. And having mouse-overs to get basic information and flip back and forth if I want to compare is a pain. In the end, whatever, I'll figure it out, but even after using it for a month, I find it a much less pleasurable experience.
Being dismissive toward people who had no say in this and are now experiencing a lot of issues isn't really helpful nor does it make the changes seem less problematic.
