I feel the sudden need for a new xml file format that we can put our web pages which details which books are in our libraries, various meta-data, including a rating. Would make getting an instant understanding of the strengths and weeknesses of another geek fairly instantaneous.
(head in clouds mode on) That would be neat. It'd have to be very simple, though. Title, Author, Publisher, ISBN. You could then have a "book aggregator" that monitors blogs of nerds with similar tastes, and notifies you when one of them has read a new book.
[Later...] Being serious for a moment (HAH!), I suspect a problem with trying to write a book just about XUL is the role XUL appears to play in Mozilla. XUL appears to be an xml'ified and application specific .xresources file, with the addition of javascript to make things fun.
I've never done X programming - to me an xresources file was just where I chose what colour things should be, so I can't comment on its similarity with XUL. XUL is to Mozilla as Swing is to Java - it's the whole front-end.
But yes, that's the problem with the book. It shows you how to lay out a GUI, how to style it and make it do things with Javascript, how to write a skin for Mozilla, even how to bind your XUL to an RDF document using XBL. But it's very light on how to use XUL to make Mozilla do interesting things. Which in one way is fair enough - you buy a Swing book to explain Swing, not to tell you how java.io works. But on the other hand, it would be different if there was no book on how java.io works that you could get instead.
