Google Wave
Have you heard about this or perhaps are already participating?
It's currently in limited preview. I watched the "loooooooong video" (1:20) last night and it is quite impressive! My son-in-law got an invite from a friend of a friend of his brother's and has been playing with it for a little while. I have a feeling Google has another huge hit on their hands with this one.
Once this goes live, it'll be interesting to see how we might use this with Wikidot. If you can make the time, I highly recommend watching the video.
