As far as I am aware, Google Wave still lacks the promised ability to embed Waves into web sites. What is the point of collaborating with people, if the results can not be published? Even though there is an API, and open source, Wave is effectively a walled garden. Sure, the rest of the web can be brought into Wave, but Wave can't be brought out to the rest of the web.<p>Just about every use I have for Wave depends on this one thing. The ability to publish, share, and embed waves outside of wave.google.com. If they actually added it, I'd probably be using Wave like crazy. Without it, no matter what other functionality they have, I have no use for Wave other than as a curiosity.
