bannerfy.js
Love @FilmCritHULK's incredible essays but keep tripping over the
obligatory HULKSPEAK? Tame the beast with the Bannerfy bookmarklet.
Like Banner, it's not perfect, but it's better than the alternative.
JavaScript taken from http://bit.ly/al5qDV but heavily modified.

Compatible with any browser that supports `document.querySelector()`.
