I "like F#" but there are a few layers between my having some fun a few times a month and a business adopting it. F# makes sense when a) functional programming has a history of being advantageous in the domain, b) there is a mandate or clear advantage to develop in the .net ecosystem, c) a founder or engineering team has serious expertise with F#. Even then you have to ask if a functional-ish C# codebase you can easily add 50 developers to if needed is good enough.
