Listen, this is a pretty cool thing. Google Wave also has a public timeline, like twitter. It shows all wave created and updated if they are marked “public”, and this happens real-time. You can open these waves and join the conversation. To access it, all you need to do is, type “with:public” without quotes, in to the search bar.
One day after the beta account invites were sent out to thousands of users for preview, the wave public timeline is full of people excited about their new wave accounts. I can see new waves appearing every second.
