I don’t think these services can replace Google Wave.

you can pulling all of them together, but they are different services, they are not waves.

You can create a new docement in google docs, but you can’t talk about it with coworkerss in place.

ps: google docs and groups are blocked in China, what a [profanity] times!!!

I wish google will bring us a new wave that usable an lightweight.
