  In 2012, let’s stop talking web design and start talking product design

“My hope for 2012 is that some of the old guard of well-respected web gurus stop talking HTML and CSS and start talking serious development. I love the way many of the old guard write and evangelize, but I’m tired of discussing basically the same stuff we were in 2006.” I wasn’t specifically referring to Jeffrey Zeldman, but he (somewhat arrogantly) assumed I was, and responded with a sarcastic, “And a merry Christmas to you, sir.” ...
