What does HackerNews think of incubator-retired-wave?

Apache Wave is now retired

Language: Java

FWIW, they donated the project to the Apache Foundation, so it is open source (albeit unmaintained).

FWIW iirc it was continued for some time by apache (https://incubator.apache.org/projects/wave.html) but is also discontinued now. (I hope thats the correct project, but I'm pretty sure).
