I like the CloudFoundry report [1] better as a reflection of what businesses are actually using rather than search engine metrics (TIOBE) which are overly influenced by controversy and search engine methodologies than actual usage. However it's no prettier a picture, almost no functional languages in the list at all, only Scala making a significant dent (and you can debate whether that is functional or not). Other JVM languages like Groovy are significantly ahead of Clojure in all rankings.
