Jeremy Keith has written a terrific primer on the importance of embracing the web we have and designing with open standards ("material honesty") and, more importantly, content in mind. It's a great read, even (especially?) for non-designers.
Coincidentally, over the last week or so, I've been making some changes to my personal websites (here and johnke.wtf) to make them more responsive and behave nicely on different devices. So this has come along at just the right time for me.
