Google Wave is an innovative new communication tool, but part of innovation is that it's not always intuitive to use. Early adopters have been jumping into Wave with little guidance on how to take advantage of all its features. I guess you could watch the 90-minute Wave video, but that's not exactly a quick-start guide.

Well, there's a saying almost as old as computers themselves, and it goes: RTFM. Read the, um, flippin' manual. Now Google Wave has a flippin' manual that you can read, but it's not from Google: it's from Lifehacker's Gina Trapani and Adam Pash. Sounds a lot better than "watch the frickin' 90-minute video," eh?

Gina and Adam's guide is quickly making the rounds on the web, being promoted by the likes of Mashable. I'd like to add Download Squad's endorsement to the list. The Complete Guide to Google Wave is a straightforward, well-organized volume that goes a long way toward demystifying a new and complex tool. It's available to read online for free, but you'll be able to buy it as a DRM-free PDF soon, and in print in January.
