Some time ago I said I'd post here about my experiences with Google Wave. Well I didn't really have much experience! I just couldn't find a way of using it that suited me and I couldn't find any advantage of it over other collaboration methods. I use Google Apps and the shared documents, email and chat features easily satisfy my needs.
Now Google has announced that they're not going to be developing Wave as a separate product any more, so I guess that's that. I'm sure some of the technology will make it's way into other Google products but in the meantime I'm laying my use of Wave to rest.
