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.
Google Wave Public Timeline
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.
Invites to try Google Wave, the revolutionary real-time communication and collaboration tool, started going out around ten hours ago. If you haven’t got one yet, be patient – you might still be lucky.

The Google Wave preview has officially been scheduled to open up to the public on September 30th according Wave API Tech Lead Douwe Osinga.
