Most of my writing effort has gone into The Lift Cookbook, and one thing I missed was why you might be interested in Lift.
That’s now fixed, via a three-part series of short posts over at programming.oreilly.com:
A Birds-eye View with Lift: Organize and control content with the Lift web framework.
Squeaky Clean Ajax and Comet with Lift: Focus on application development, not the plumbing.
Hope you find the framework as fun and productive as I do.

The Lift Cookbook in PDF, on Kindle, print, via the Play Bookstore, and in iBooks.
