Google Wave is a young tool that's not terribly easy to understand for a lot of folks, but at least a couple of your Lifehacker editors are completely nuts for Wave and its potential. The DRM-free, 102-page personalised PDF of The Complete Guide to Google Wave is available for six bucks American, but keep in mind that the content of our book will always be available for free at any time at http://completewaveguide.com/.
The preview edition is just the start. We plan to release the first edition of the guide in early 2010 as both a PDF and a softcover print book, with new editions to follow throughout the year as Wave evolves.
For a quick look at why we're so excited about Wave, check out Gina's keynote speech at the Web 2.0 Expo this week in NYC, and follow @gwaveguide on Twitter for a regular stream of useful Wave tips and for updates on the book. If you do decide to purchase the PDF, you have our sincerest thanks for supporting our little project, but as I said, it's always freely available on the website. Beyond that, we're all ears for suggestions on how we can improve the guide in the comments.
