As someone still inquisitive about Sydney, I'd actually rate this site highly for the photos. Looking at this page alone I can see a heck of a lot that'd interest me (seeing as I do historic research into buildings, including phases of construction materials, style etc.) You saw me gazing up at the ornamentations at the top of the buildings while I was there, TLD, viewing the stone artwork that no one aside from us nutty historians pay heed to -- it'd be way worse now.
