The animation that makes the header disappear is kind of weird, but what other UI madness are you referring to?

The most annoying is that scrolling can change the article without warning, and scrolling in the opposite direction may or may not return you to the article you actually wanted to read. Maybe it depends on the browser, but I have the same behavior on the Android browser and desktop Firefox.

Doesn't it just load the next article when you've finished the current one, infinite scroll-like?
