Google has really out done themselves on this one. Watch for the Spell checker (which is revolutionary) and the real time language translator (allowing communication with people from all over the world in real time, without learning a new language).
I have already signed up to get Developer access to Wave and hopefully the fine people at Google will grant me this wish (Since I was unable to attend GoogleIO). I can only begin to imagine the possibilities that a platform like this can bring. I am going to dust off my Java skills and get to work on some extensions!

Developers, let me know what you think. Are you excited? How bad do you want to get your hands on it?
