The Clojure community is active, growing, and always helpful. Over the years, the primary communication mechanisms have changed along with the industry varying from IRC to the mailing lists to in recent years, Slack. We’ve been tracking this for a couple years now. Slack continues to be strong with 64% of respondents using it (note that this may be biased by where we advertised the survey!). The Clojure subreddit continued its strong rise to 55% use. ClojureTV on YouTube was a new answer this year but almost half are using it to watch Clojure videos. The official Clojure mailing lists had another drop this year as people shift away from "old school" mailing lists. And the original place where communication happened for Clojure is IRC which continued to fall out of use, now at only 7%.
