Google Wave, which combines IM, email, and wiki-style editing goes on public trial today with 100,000 invitees, each of whom can nominate five more people to "join the Wave".

"We found we could build a flexible tool with a surprising amount of functionality," Mr Rasmussen told BBC News.
Watch the looooong video you'll understand why I'm so excited about Wave.
