edit: yeah, it isn't intended to be programming specific: "Indeed.com searches millions of jobs from thousands of job sites.
This job trends graph shows the percentage of jobs we find that contain your search terms."
Under the graphics you have the links to the respective jobs. Just check for yourself what these "Go" jobs [1] and the "Scala" jobs [2] are. "Haskell" jobs are also interesting.
And more: don't forget that currently even Php ads feature the infamous "experience with functional programming (Lisp, Clojure, Haskell) is a plus" line.
