I’ve been spending a little time with Google Wave over the last week or so – nothing much, just very light puttering about. I think there are issues about persistance, vulnerability of public waves to vandalism (much more fragile than Wiki), and a general messiness as folk try and figure out how to actually use Wave productively. Basically I haven’t got very far with it.
Meanwhile, other folks are already thinking about how to use Google Wave as the underlying protocol and communications architecture for… stuff. Prime example: AR Wave – building a distributed Augmented Reality system ontop of Wave. (In following this, I also discovered that it is possible to embed a view of a Wave in a web-page – as here.)
If you have Google Wave access, you can hopefully join the wave here (hope the link works!)
