I think you are the first person I know of, who actively uses Google Wave.
Adelene Dawner and some of my other friends use Google Wave too, but mostly to read stuff I wrote, and to comment on it, or chat live about it.
Oh, and another friend, MetaFire Horsley, aka MetaHorse, uses Google Wave to write some awesome sci-fi stories, and get live feedback on them. And that's working pretty good.
I might as well ask: does anyone else here use Google Wave? Or does anyone here have a Wave account that they're not using because they don't know anyone else who uses Wave?
oh, and here's some more information about what I'm using Wave for.
It has been claimed on this site that the fundamental question of rationality is "What do you believe, and why do you believe it?".
A good question it is, but I claim there is another of equal importance. I ask you, Less Wrong...
What are you doing?
And why are you doing it?
