You have Go listed for Twitch, but justin.tv launched in 2007 and Go didn't exist until 2009.

Can we also submit it via HN? If so, my understanding is that Pagerduty is running and long-term invested in Elixir (https://www.pagerduty.com/blog/elixir-at-pagerduty/) and Podium has migrated from Ruby to Elixir as the main stack (https://medium.com/podium-engineering/two-years-of-elixir-at...). Thanks!

Edit: oops, I see now it is the initial language. Indeed PagerDuty started using Elixir only later on. Although one could argue Elixir was part of Podium in its initial growth.
