Latacora has its token Clojure person: me. I write Clojure every occasion I get, we've shipped Clojure code to customers, et cetera et cetera.

Most of the stuff I'm doing in Clojure would be possible in other languages, but in a sense that's only one notch below "Turing tarpit" possible. So, in the only sense that a startup should care (would you f'ing ship it?): only possible in Clojure or a handful of close cousins.

I'm hearing less about it on HN these days? But it was a great language yesterday, remains one today, and there's constant development of tooling and community :)
