I’ve been thinking over the last few days about what Google Wave could be used for. Obviously it can be used as a document collaboration and review platform. It can also be used as a multi-user chat program, although there are probably other existing programs that are just as good for managing that. Some people have claimed that it isn’t anything revolutionary. In and of itself, this is true, as it just takes concepts already available in email, instant messaging and collaborative documents and puts them together.
