I agree, this is an amazing site. Just the thought and determination to record these buildings on the brink of their extinction is an exciting and worthwhile project. It's exciting to see what's been left behind (in some it looks like the staff literally downed tools and walked out, with twenty or so years passing untouched).
It's photography with narrative for the curious, letting us see more than what we're supposed to or allowed to (if you're not the curious type, or you go for more obvious beauty then I suppose it is just boring and ugly?)
Personally I hate obvious photography. These endless shots of flowers and sunsets etc. hurt my eyes (I prefer to just see them in real life), but each to their own.
