21. — Ethan Marcotte
    Now more than ever, we’re designing work
    meant to be viewed along a gradient of
    different experiences. Responsive web
    design offers us a way forward, finally
    allowing us to “design for the ebb and flow
    of things.

26. — John Allsopp
    The control which designers know in the
    print medium, and often desire in the web
    medium, is simply a function of the limitation
    of the printed page. We should embrace the
    fact that the web doesn’t have the same
    constraints, and design for this flexibility.

    Shoot me now…responsive design has
    seemingly become confused with an
    opportunity to reduce performance rather
    than improve it.

    I doubt anyone really wants to release a site
