» There are Apparently Lots of Haskell Jobs... #
... and some of them even involve trees.
A while ago, Rod Johnson asserted that Spring had overtaken EJB as a job requirement for Java developers, supported by some charts from indeed.com. (For follow-on analysis, see an article on InfoQ.) I'd call the Spring or EJB decision a false dichotomy in any case.
On a lark, I decided to try a three-way competition between Haskell, Erlang, and OCaml, with Lisp and Pascal thrown in just because, and the results surprised me, since I expected Erlang to beat both Haskell and OCaml:

So, what are these Haskell jobs...?

Ah. A more reasonable query (like "haskell and functional") gives the expected results of a few jobs in financial services. The most intersting thing about the query is that twelve jobs is about 0.00025% of the total number of jobs in the engine, so I'll guess that they have on the order of 4.8 million jobs and thus that there are around 9,600 jobs (0.2%) listed for "spring and java" as requirements.
