This is so cool. I see you used Erlang for various components like the UI, was your primary reason for using Pony instead of Erlang for the data processing performance? That seems like a safe assumption given Erlang's frustrating performance characteristics. There isn't a lot of information out there about Pony vs Erlang in production, hopefully you guys will write up more in the future about the differences you have encountered.

Thank you for your kind words. It's nerve wracking when you finally pull the trigger and say "we need to get this out there".

Re: Pony vs Erlang.

Point 1: we love erlang.

There's a short version of the answer to your question starting around minute 49 of my QCon NY talk: https://www.infoq.com/presentations/pony-wallaroo

And yes, I am planning on writing more about why we went with Pony (which led to my becoming a member of the Pony core team).
