I was a bit skeptical about Google Wave when I saw a friend mention it on his Blog. What would email/communication be like if it was built today and not 40 years ago?

Having just seen part of the Google I/O presentation all I can say is wow.

Looks good. Builds lots of different ideas into one system - including a tool which would revolutionise blogging to a certain extent (or atleast make it much more open and easy for people to reply and keep track of things without ever having to go to the blog in question).

Google Wave is planned to 'Go Live' later this year.
