I started writing OCaml in college after hearing a talk by Jane Street [0], one of the most outspoken corporate supporters of OCaml.
After getting past the steep learning curve (about a weekend of pedal-to-the-metal debugging), I really got a feel for how beautiful OCaml semantics really are.
If you're looking for a solid and familiar OCaml stack, check out OWebl [0]. Always looking for helping hands or other support.
