Sigh. Completely unreadable on iPhone. Locked viewport with half the content off screen. Mobile site design never tested on mobile device considered harmful.
I don’t want to be a jerk, but I had similar difficulties reading the content.
My last resort move in these cases is using “reading mode” (and eventually send to instapaper).
It wasn’t even wide enough for my Galaxy S4. I lost a few words off the side. I tried different pages and it got worse.
And you don’t even have to have a mobile device. Just use the chrome mobile development mode or Firefox developer edition.
As someone in charge of ui on a website, I am paranoid about these things and check on my devices as well as chrome.
