I assume you've asked them, but what did they say? My guess: Haskell has a very strong academic background. I know it's very popular in the language design community, I mean, it's basically lambda calculus with a very advanced type system, and academic language designers love type systems. Clojure is dynamically typed and is has all the messy compromises of a pragmatic language -- that's my guess.
