It's not surprising that landscape features strongly in APUG in the form of large format photography.
Landscape as a genre offers a rich metaphoric space for visual commentary on virtually everything except perhaps the minutae of ever shifting personal relations. The messages of landscape are carried in its textures, tones, and spaces and these qualities are just what the slow but fine large format camera accesses better than anything else.
But it's not all one thing at APUG. I bet there are even some beguiled members of the Henri Cartier-Bresson fan club here, maybe a Minox enthusiast or two, and doubtless some digital lurkers. E pluribus unum and all that.
