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?
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.
