The engineering blog of Takipi, a Java debugging tool company, covering Java, JVM tooling, libraries, and production debugging.
HN links it for Java and JVM posts, including debugging, JSON library comparisons, Dropwizard versus Spring Boot, and Java 10 features.
Most companies don't really publish their tech stacks in the first place. However, there are a number of consulting companies, such as JUXT and Metosin, who built their entire business on Clojure consulting. Clearly there is a market for it, and if you look at the clients of these companies it's quite clear that it's not just some one off projects.
There are plenty of companies that are switching to Clojure all the time, and feedback is overwhelmingly positive. Here's a recent example https://blog.takipi.com/clojure-at-scale-why-python-just-wasnt-enough-for-appsflyer/
Again, my personal experience is that my team grew from 3 to around 20 people now all working exclusively with Clojure, and we've never had any problems onboarding, or being ideologically aligned.
Just because it allegedly didn't work out at Amazon doesn't really translate into sweeping assertions you're making about it.
This is a weird link to advertise Java 10 to developers. Instead, a short google search brought me https://blog.takipi.com/how-java-10-will-change-the-way-you-code/ and the heading picture https://384uqqh5pka2ma24ild282mv-wpengine.netdna-ssl.com/wp-content/uploads/2018/02/Java10FeatureHighlight1-1.png probably explains type inference more or less without words :)
The Takipi blog deals a lot with debugging related issues: http://blog.takipi.com/

Without turning this into a long tangent subthread.. could you point to some support for this? The comparisons I've seen are more nuanced.[1]

Also, saw this comparison of Dropwizard with Spring boot: http://blog.takipi.com/java-bootstrap-dropwizard-vs-spring-boot/ Interesting to understand the libs and flexibility each one have.
