What is Google Wave? The latest from Google Labs, for now available only as a limited-distribution preview, Google Wave is what? The ultimate collaboration tool? Really superior e-mail? The most ambitious (and confusing) web application ever created? These things and more, according to The Complete Guide to Google Wave. The Guide itself is a free, ever-changing experiment in publishing that seeks to explain one of the most elaborate and bewildering Google inventions of all.

The Guide is written by Gina Trapani with Adam Pash, both of Lifehacker fame.And it’s also written by you, if you care to join? The online version of the Guide will remain free and be updated continuously. The Guide will also be available eventually as a DRM-free PDF and an independently published softcover print book, due out early next year.
