On August 4, Google announced that it will cease development of Google Wave.
Wave has not seen the user adoption we would have liked. We don’t plan to continue developing Wave as a standalone product, but we will maintain the site at least through the end of the year and extend the technology for use in other Google projects.
In all likelihood, Wave was a little ahead of its time, and a little too complex. It'll be back, we're sure.
Now that its gone, what real-time collaboration tools will you be using? Please comment below.
