Fantastic article about the hype and truth of Web2.0 by Jeffrey Zeldman.

“We pause but a moment to consider two AJAX-related headaches.

The first afflicts people who make websites. Wireframing AJAX is a bitch. The best our agency has come up with is the Chuck Jones approach: draw the key frames. Chuck Jones had an advantage: he knew what Bugs Bunny was going to do. We have to determine all the things a user might do, and wireframe the blessed moments of each possibility.

The second problem affects all who use an AJAX-powered site. If web signifiers and conventions are still in their infancy, then AJAX-related signifiers and conventions are in utero. I am still discovering features of Flickr. Not new features – old ones. You find some by clicking in empty white space. This is like reading the news by pouring ACME Invisible Ink Detector on all pieces of paper that cross your path until you find one that has words on it.”
