Hi there,
just this month we hit a point, at which we were confident enough to release this and now we're even more confident, so we put it on HackerNews.
If you care about our techstack: the backend is built using rails, em-websocket and postgres, while the Frontend relies on angular with some Backbone leftovers. Messaging is done via vanilla websockets and protobuf.
Every kind of feedback is welcome, however harsh. Thanks!
