google wave

http://wave.google.com

For those who don't know google are currently developing a web tool called wave. Basically its the replacement for email. Its a collaboration tool, instant messaging service, email service, app hosting service and more all rolled into one user friendly tool. There's so much to it that i would be doing a diservice to try and explain it fully- there's a long but fascinating video on the wave website

I for one, think this is the best thing every and can't wait to be able to use it
