You should not be so narrow sighted that you assume people do not comment because they wont accept change, that is not how internet habbits works.
In a way, you need to view traffic as customers (even though you do not make money on us), first task is, why do you want traffic on amiga.org?
Let us assume, (that partly), you want traffic on amiga.org because you want users to upload images other users can comment on.
In the situation we have right now, the earlier version from 2001 was better suited to that objective - to get users to upload images and to get users to comment images, I can only speak for myself, one of the reasons I posted images was to read comments. Now I tried it once and got zero comments so I am not likely to be so eager to upload images as often as before.
So in order to adapt the site to suit your customers better (if we asume that you want the gallery to grow both by uploaded images and commented images) the gallery part needs rework to make it more appealing for visitors to use it again.
That has got nothing with peoples resistance to change, or people upset over the move to the new system, it is just the way it is.
Isnt it great that amiga.org have users that can give you this input for free on how amiga.org can be improved to better suit the community?
