## Why people recommend it

- Fault tolerance and graceful crashes (3 comments in the sample): "fault-tolerant languages such as Erlang/Elixir allow me to not worry about the billions of edge-cases" ([source](https://news.ycombinator.com/item?id=48286505)) "letting things crash gracefully is so useful" ([source](https://news.ycombinator.com/item?id=45977973)) "has a resilient environment with hot swapping" ([source](https://news.ycombinator.com/item?id=49152016))
- Safe, scalable concurrency (2 comments in the sample): "Erlang/Elixir will probably become more relevant as people move into massively parallel constraint solvers." ([source](https://news.ycombinator.com/item?id=49407196)) "Safe language, safe concurrency, immutable, scalable" ([source](https://news.ycombinator.com/item?id=49269128))
- Actor model fits problem spaces (2 comments in the sample): "the actor model implemented on top of a stable core (eg. Erlang/Elixir on BEAM) might be a natural fit" ([source](https://news.ycombinator.com/item?id=47033159)) "Erlang's computing vision lends itself super well to this problem space." ([source](https://news.ycombinator.com/item?id=47145858))

## What people warn about

- Multi-host clustering is immature (2 comments in the sample): "much like Erlang/Elixir the multi-host parallelization is not cleanly implemented… yet..." ([source](https://news.ycombinator.com/item?id=47803822)) "Clustering on OTP was certainly an area even seasoned gray beards tried to avoid." ([source](https://news.ycombinator.com/item?id=49566906))

## The badge

A product earns the Hacker Approved badge when at least 10 people recommend it, recommenders outnumber critics at least 2 to 1 (mixed feelings count toward neither side), it was recommended in at least 4 of the 12 months and in at least 5 different threads, and no single thread supplies more than half of the people who recommend it. Health and money products are never badged.
