With Advent of Mobile, Liquid Layouts Grow More Important . . .

Anecdotally, for starters, I've never seen a site do this for mobile.
Even sites with robust liquid layouts cannot be expected to condense to fit in 480px. At that width even ubiquitous things like a 2-column layout don't work well. Displays that small need a different approach.
I would rather have a site that retains its standard look and feel but easily lets me zoom into the content I'm interested in than a site that tries to squeeze it's multi-column layout onto a small screen.
