I've been teaching myself J and dabbled in a few other APL-family languages before that (Klong and Dyalog's APL mostly). I don't have any specific goal in mind and have been doing it for fun more than anything -- I recently tried writing a minimal ray tracer[0] for example. I've been surprised at how much I liked writing it. J can be derided for being a "puzzle language"[1], which isn't entirely unfair, but I've found the paradigm of array programming carries over into more widely used languages and libraries ("Iverson ghost"[2]). I wouldn't bother learning to put it on a resume, I would try it out for fun.
