So google is shutting down wave, or at least abandoning it. Ashame.

I use Wave and love it. I use it mostly for taking/sharing notes on projects or classes. There are a few scalability issues when waves grow beyond a certain size but, aside from that, it works great and is very easy to use.

I added a DISCONTINUED flag and more information on the future of Google Wave to the app description:

"Google announced in August 2010 that there were 'no plans to continue developing Wave as a standalone product', but that they would 'maintain the site at least through the end of the year [2010]'.
(source: Official Google Blog https://googleblog.blogspot.com/2010/08/update-on-google-wave.html ).
In September 2010 Google described its plans to develop the Open Source'd code into a standalone version (server and client) that would allow running Wave on your own hardware (albeit not with all features). (source: Google Wave Developers Blog http://googlewavedev.blogspot.com/2010/09/wave-open-source-next-steps-wave-in-box.html )"

I've got my account, and I'm starting to connect with people on Google Wave. There's a bit of a learning curve, and it's going to be a slow start for all of us using it. However, this is a new protocol that's going to have an impact on the way we work together and communicate online...it's very exciting to be in on this!

never did find a use for wave while it existed but it was cool while it lasted..
