I can appreciate your desire to share the good news about Clojure adoption, but I don't think the language is in need of defense. It's used a lot all over the place, and you shouldn't feel the need to convince others of that. Because even if it weren't used hardly anywhere, it would still be a great tool for those of us who do use it. That it is in fact in use in a lot of places, regardless of its specific role, is just a nice added bonus.

If someone doesn't want to use it for this reason or that, it's their loss not ours. Those who need to find Clojure eventually will, because there is nothing else like it.
