Whenever I see OCaml brought up, it is nearly always by Minsky. Is it that very few people use it in general? That it is particularly well suited to the problems a private hedge fund faces (oxymoron I know, but I don't know how else to describe Jane Street)? Or that Minsky just happens to be vocal in the internet circles I tend to gravitate toward?
Jane Street is a `prop shop' in the lingo of the industry.
You are right, OCaml doesn't see too much use outside of Jane Street, Citrix and a few others. I think the academics mostly left it in favour of Haskell. Also the owner of the OCaml project didn't embrace community development early on. It's more like a cathedral than a bazaar. They are signs showing to change, but it's probably already too late for mainstream popularity.
