The Ballmer Peak XKCD suggests that it's a graph of ability, rather than bug frequency, which should be inversely correlated with ability. A simple change of the wording fixes this terrible mishandling of Ballmer Peak data.
I find myself often using (modified) examples to test in IE and it's a pain to have to add the shims in every time. Might as well just add them in always.
onInput has the advantage that it responds to repeated key events before
onKeyUp and is called when modifying the input without the keyboard
(such as pasting with the mouse).
Test Plan:
Opened the ballmer-peak example and docs homepage in Chrome and checked
that both examples update whenever the text is changed.
