I don't really understand how a site worth billions has such bad programmers. Everything about it is bad. It's slow, it crashes frequently, basic things go missing like the image you were trying to view, you frequently get "whoops that page no longer exists" simply reopening your browser on a thread you were viewing the previous day.
But go to the desktop version, and it all works fine.
They even inexplicably implemented AMP, even though the whole point of the site is up-to-date comments, not a cached one sitting on google.
The only competent part of their team seems to be ops, as it has finally stopped falling over.
