I signed up last week and have been using it to learn Erlang. I have some experience with Elixir so Erlang isn't totally foreign to me. I'm experienced dev and have only commented on 1 submission. The problem with commenting on submissions is that I'm learning the language as well so there lacks the authority of knowing what would be the <INSERT LANGUAGE> way.

Thanks for the reminder; I used to do some Erlang commentary on the site, will go look again.

I had a lot of good feedback on some Ruby problems I worked on a few years ago. I'm guessing it's highly dependent on having a community for each specific language.

Same, on Ruby and Lua I've gotten good feedback, but not other languages. I think it helps to comment on your own stuff and ask questions if you're unsure about your solution and if there's a better way.

I've written ~15 of the higher-level reference exercises for Elixir on Exercism, and do try to comment when I can, but my day job keeps me from it a lot of the time. Some sort of reminder system would definitely be great, especially as more people use the site.

I've had better luck with getting reviews when I form or join teams.
