While the content is great, the tech seems bloody awful. Why is it so slow to load? It takes 5-10 seconds to load on both my laptop and my desktop (both < 1 year old) and I have nice fast fibre. Why would you start with a loading screen in this day and age? And worse a loading screen that doesn't tell you what it's loading. Flash is dead.
It severely impacts the usability, it looks like nothing is happening and I can imagine a lot of people just close it before it loads.
And it's (virtually) static content! Why doesn't it load with the opening page at least?
