I found 1M messages/day rather too low. So I checked the video, sure enough they have 1B messages/day using close to 10Gbps at peak, with 100+ servers. A correctly built (epoll/reactor based) C/C++ based system should be able to handle that with ~10 servers. I suspect that erlang is successful despite of the language itself, mostly because it's also a mature product: a well tested production quality actor system with decades of tweaking. I liked the Q&A especially whether a better type system would catch the "horrible bugs" they had :)
