Google Wave: email done right?

[gusl]

Thanks to Jon Elsas, I now have a Google Wave account (but no invitations). It seems to just be an alternative to email. Like GMail, it seems to be based on the idea of grouping emails into a single conversation ("wave"), and it supports different types of reply, in a way similar to LJ. It also eliminates the need to forward emails to late-joiners (like a mailing list archive does). Like protected wikis, it's never too late to fix or reorganize the content, and anyone in the team can do it.

If it's intended as project management, it seems to be missing a lot of the features that QTask has, like assigning and accepting tasks.
