More and more its looks like an abandoned project. They put eggs on it. Zero response from them.
I'm not sure where you've gotten the idea of an abandoned project, but allow me to clarify a few things,
Currently, we've started development on the networking layer of Rebirth. This month, we'll be aiming to publish a whitepaper for Rebirth broken into segments for release and review by the community. We're open to feedback and criticism and of course we're open to adapting based on new information and ideas that come to light.
We're also actively looking and forming connections with press related marketing personnel as we begin our development in 2017.
It's but a matter of patience

I mean maybe not tottaly abandoned yet, but it looks like slowly forgotten. Just look at your frequency of post. Its one post per month. Here is Dec 20,2016 and Nov 18, 2016. On slack isn't better. Last note is from Dec 17. I don't think it's good. I just suggest more involvement in contact with us. Short note about progress or what are u doing. It isn't take much time. It is not about patience, cus I have it. I can wait even 2 years, but I prefer when devs share with us what they do. I will wait little more before I make a decision, so we will see.
