Khoi Vinh on the difference between print and web design

Khoi Vinh sums it up very well for me in his article.

Still, even these basics are the second step, in my view. The prerequisite for doing something meaningful with any of these skills — HTML, CSS, Flash or whatever — is first embracing the medium as something different from print. Indeed, there’s no point in learning these skills unless as a print designer you’ve made a prior shift in your understanding of how design works in digital media. Specifically, come to grips with the fact that, on the Web, design is not a method for implementing narrative, as it is in print, but rather it’s a method for making behaviors possible.

More often than not, the reflexive approach that I’ve seen print designers take on the Web is to treat it as a vehicle for print-based design practices: fixing type sizes, specifying typefaces, ignoring usability and expediency, and perhaps most notoriously making the assumption that, over time, users will come around to a print-focused way of consuming content.
