A List Apart is an online magazine devoted to designers who make websites and their uber-technical alter-egos. A List Apart hosts a library of intelligent articles and technical resources regarding W3 standards, browser compatibility, CSS, accessibility, and the “meaning” of web content. I especially love ALA’s section on Usability, boasting 56 articles discussing the theory that “Usability experts are from Mars, graphic designers are from Venus.”
