My apologies. The home page does still appeal for explorers, photographers and historians. Mea culpa!
There seem, maybe, to be two issues here:-
1. Semantic definitions, such as mine, quarry, pit etc. This, to a great extent, could/should be defined by the Aditnow Dictionary.
2. Site structure, useability etc. This, methinks, is ultimately up to Simon, if only because, he will have to implement and service any site upgrades. This is an area in which I profess to profound ignorance and great admiration! On that basis, I tread lightly!
It would be very helpful, within the present album structure, if all contributors were to annotate their pictures, if only with key/search words and a cross reference, if req'd. If done, might this allow keyword searches?
I don't know how many visit the site and what/why they do but I suspect it could be large. Are we, registered site users, actually in quite a minority?!
