All kidding aside, one- or two-word comments are quite uninformative. Just because the original article with its "Scala is not a well-designed language" statement doesn't bother backing up bold claims with arguments, we should not fall into the same trap here on HN.
It's worth talking about Clojure as an alternative to Scala. They're both targetting the JVM, and they're both still on their way out of a niche. But just throwing out the name of an alternative programming language doesn't make a useful comment yet, nor does the "too succinct" reply.
