I opened it up in IE with no problems, and was surprised to find it a little faster than Chrome - but IE is my fallback browser and I don't have any extensions or addons loading there for that reason.
I didn't especially care for the 'start' tab. I would let the titles fly in behind the image as before, but on touching the image anywhere I'd then shrink the cover photo down to its tile and have the others fade in.
As for the project itself, once I could get access I was impressed - it did a good job of bridging the gap between magazine and web presentation. I really liked the simple but effective page navigator buttons which are presumably optimized for tablet use but also saved me from tedious scrolling on the desktop. The ToC was good too, although I would have liked an easier way to get back to the initial tiled layout, which I preferred. I did not like that different tiles took me to the same articles on some occasions. I didn't always read the captions before clicking, and was confused to find myself going back to articles I had already read.
Overall I would give it 7 out of 10 (overlooking the access problems mentioned above, which I think need to be fixed as a priority). Although I'm not the target reader and found the writing a bit gushy, there was a good balance between visual and textual content that was well realized in the interactive context. The only negative I felt while reading the magazine was the sense of being constrained by the vertical page orientation on a desktop monitor, resulting in a lot of empty space on the sides, a pet peeve of mine.
If there was some way to show two pages side by side (like an actual magazine) I would give 9 out of 10. to me one of the great joys of magazines and books is being able to open them wide and feast one's eyes on well-balanced horizontal layout - I've never understood why some people like to fold the spine over and only do this very occasionally. I feel like the single-page paradigm is a path-dependent one that has been driven by the screen size limitations of devices like Kindle and various tablets, but which leaves me feeling like I've lost an eye. I hope you could explore this in future iterations; given the subject matter of eh magazine it seems like a natural candidate to try out these ideas. I felt a bit sad that nothing inside the magazine matched the powerful visual impression of the frame-filling intro photo. Browsing the photo stack that was in some articles was an inferior substitute and didn't take full advantage of available screen space.
