Left after 10s, because of the loader spinning and nothing happening.. If there would be an indicator of how much time I need to wait for page to load, I've might stay.
I ended up waiting a bit longer.
I checked the console, for me the site took 35s to load. There were 142 (!!) requests and 18.1 MB file transfer!
Their specimen pages are so damn beautiful. Check out GT America too. This is how you present type on the web.
The pristine quality of this typeface alongside the absurd performance of its website caused a deep turmoil in my soul.
