In the comments on Deane’s latest bit of Spolsky-worship, I had postulated that, given the idea that thick clients for the web can provide a better experience, and Firefox’s increasing market share, 2006 could become the year of XUL.
There was a great link posted on digg this morning that illustrates this. Firefox users, check out MAB, a XUL-based Amazon search interface. (After you click through, click on the ‘launch’ link on the right).
There you have it. A thick client that runs on nearly any OS, and requires no installed components other than a Mozilla browser (and with Firefox’s popularity, that may already be there). What if, say, Basecamp worked this way? Or Flickr? I think we’re fast approaching the point where it would be commercially viable to at least create an alternate interface for a web app in XUL.
