Google Wave

I just finished watching the Google Wavevideo on YouTube, here. Google have come along with a new technology called Wave. Watch the video to find out more about it (be warned, its a video from the Google I/Odeveloper conference, so its a little techy). Basically they have stepped back from the way we currently communicate with each other (e-mail, IM, SMS) etc and, reinvented it. Its hard to explain, just watch the video(its long though).
