Seems to be the same thing with Haskell and other languages, including Golang, that many groups on HN are passionate about. There aren't many people hiring for skills in these languages. Some start-up founders I know who have built their company on Python and Javascript, when I ask them if they have looked at Golang, they reply 'What's that?'.
Yeah I don't see many positions for Haskell, either (and I'd like to). OOP class systems are so irritating when you could get more powerful type-checking from less boilerplate. Maybe I should look into F#? AFAICT it seems to be Haskell's sister, who left academia to do finance and is pulling seven figures in her early twenties.
My group in Azure is hiring. I don't think we have any Haskell in production, but I sure bet we could get away with using F# and the new immutable collections for a lot of new stuff. zip [marshray@; maray] [live.com; @microsoft.com] Email me, I'd love some coworkers who were really into FP.
Haskell is even older, but you don't see many job ads for it. I don't think it has much to do with the age of the language. Node.js is an example of a very young platform that many, many startups are using. (Although, to be fair, JavaScript has been around for quite some time now.)
