How does an unusable page like this even pass preliminary design review? Perhaps the page works well on the 16-core desktop computers with giant monitors common in the ivory tower.
I'm not going to defend the design choices here but it performs fine on my four year old laptop running Firefox/Ubuntu, so it requires neither a very powerful hardware, nor Chrome which is a more common failure mode.
On my very beefy computer, but with a 10 Mbps connection the experience is kind of shitty - it takes around half a second after a "scroll" for the content to appear.
I made the mistake of clicking on the link while my kids were playing Minecraft PvP in the next room. Cue anguished shouts of "I'm lagging!" for the 30 seconds or so I spent staring at the loading icon.
It doesn't crash on my iPhone 6 Plus, but it's practically unusable. 5-10 seconds of waiting for it to respond to trying to swipe down, and horrible frame rates while it does so.
