Ajax isn't a technology. It's really several technologies, each flourishing in its own right, coming together in powerful new ways.

User-centered design means understanding what your users need, how they think, and how they behave - and incorporating that understanding into every aspect of your process.

Problems with visual design can turn users off so quickly that they never discover all the smart choices you made with navigation or interaction design.

Ajax is an important development for Web applications, and its importance is only going to grow.
