[LINK] A new design for Mark Boulton

Published On :: 2010-11-30T13:17:08+00:00

Words to tattoo on your knuckles:

Over the past couple of years, my blog hasn’t felt my own, to a degree. It’s felt like I’ve been writ­ing for an audi­ence, post­ing stuff for oth­ers rather than myself. That’s arse-backwards. A blog should be about per­sonal expres­sion. The moment you start think­ing, and writ­ing, to please oth­ers then it’s a bind; it feels less like a per­sonal exer­cise and more of a job.

A beautiful, thoughtful redesign from Mark Boulton (and a responsive one at that). Go go, read read.
