Slightly off topic, but since no one else had mentioned it, just wanted to say the rest of his blog is incredibly well done (at least on mobile.) Clicking through to his "Greece" link (http://paulstamatiou.com/photos/greece/two-weeks-in-greece/) was a great decision. Great photography, great layout/design, and good UX overall (I love how it tells a story, and keeps track of what you've seen)
