Google is no longer going to continue developing Google Wave as a standalone product, but will maintain the site at least through the end of the year. When I tried Google Wave when it came out, I was given a couple of invites that I can share to friends. Cool, so I can send an invite and try this new collaboration tool with friends. I sent the invite and got a message saying invites are not immediate and will go some review process. So I wanted to play around with this collaboration tool but no one to try it with. No wonder Google Wave is dead now.
