You may have noticed me doing research about the technology stacks being used by #ActivityPub apps, this is because I'm involved in a couple federated projects (both of which are new use cases, and extending the #ActivityStreams format).
One of those (current dayjob) is #MoodleNet (for educators to curate educational resources together), and we now decided to use #Elixir for the back-end, which I explain in detail here:

I'm open for feedback & collaboration requests!
@mayel Good call with Elixir. I use Go in my dayjob and appreciate both its concurrency and lack of robustness. Having a process not crash the whole system, and choosing Elixir over more popular languages, makes it clear that you're prioritizing robustness. That's a refreshing change of pace.
