Thanks. There was practically no feedback so far and I'm hesitant to release 1.0.0 final. Will you use IxJava in the near future extensively?

I very much intend to. I'm currently developing a quite complex app and RxJava+IxJava are both game-changers in terms of managing complexity. I'm using them mostly on the client side through GWT at the moment as that's where most of the current development happens, but I'm sure both will find their way into server side too. I was using Java 8 streams for the pull-based use-cases but I think Ix is richer in terms of what you can do with your datastreams so I happened to rewrite most of the code from the Stream API to Ix (I don't need any of the parallel stuff the Stream API provides).

I think Ix is a very good library and I believe the lack of feedback is because people don't even know about it. I tend to agree with the suggestion of @sirinath in #3 that better exposure would definitely help Ix.
