The Boston Globe goes responsive
Much as when WIRED was one of the first large websites to make use of the powers of a CSS-based design, The Boston Globe leads in pioneering responsive web design on such a scale.
Designed by no one other than the person who coined the term responsive web design; Ethan Marcotte, together with Scott Jehl and The Filament Group.
Update: There’s also a short introductory video available now.
