"Gee. Who would I wave with? I took a look at my contacts and saw that four of them were already on Google Wave. Still, I should read the other welcome message before continuing (linear or anal, I don't know which).
"The second message lead me to a YouTube video of "Doctor Wave". Volume was up full blast, so it almost blew my head off. Took me on a nice tour on the GUI, just to orient me (all of us who are using Wave so far). The video is a sparse 2 minutes, 12 seconds, just enough to point out all of the major areas of the UI but not enough to bury the audience in details. Below the playback, is a small group of links that lead to further content."
