Whether the website is created with 1995 software or 2015 software should not matter.
Can we agree that the most important thing for a commercial website is the customer experience? A company would want its site to be visually attractive, easy to understand and navigate, allow items to be found effortlessly, and provide an enjoyable experience that keeps customers coming back to buy things. I believe that was exactly the case with the old website design (with old software tools) and could have been duplicated equally well, if not better, with new website software tools. Needing to provide extra security, robustness, and support for diverse devices does not preclude preserving the good aspects of the previous website.
I don't see the "old vs. new" debate as unwillingness to change an opinion or being too stubborn to learn new methods. Rather, it's a a realization that something that used to be effortless has been replaced with a process that is much less satisfying. Many on this forum and other photo forums have uniformly stated how easy it was to simply browse the old site, just looking around, and not needing to search. KEH, in their reply, reveal their mindset has a dichotomy that should not exist. They say people complained about poor searching and so they proudly state they created a site wonderful for searching. Yet, they are baffled when now "people want the old menus back". That's because they thought the choice was between keeping the existing website organization or tossing it in favor of a search-based organization. My belief is that people loved the old organization / presentation (what they called "menus") and didn't want it to go away - they just wanted a better search, not a totally new interface.
Ultimately, the market will decide.
