Jeffrey Zeldman was one of the first designers, bloggers, and independent publishers on the web, and one of the first web design teachers. In 1998, he co-founded—and from 1999 to 2002 he directed—The Web Standards Project, a grassroots coalition that helped bring standards to our browsers.
He publishes A List Apart “for people who make websites;” has written two books (notably the foundational web standards text, Designing With Web Standards, 2nd Edition); co-founded the web design conference An Event Apart; and founded and is executive creative director of Happy Cog™, an agency of web design and user experience specialists.
In the past, people kept their expertise to themselves. Now they are sharing it very generously.
