I realize it's a bit off topic, but could you give a quick run-down on your experience with Q and J -- and particularly your perception on the potential job market?
As I mentioned above I am mainly interested in it from the perspective of a polygot/language pervert as I have been developing an APL -> PHP interpreter in my spare time (obviously for fun not production). I got into J and Q to see what the different ASCII approaches were to moving beyond the APL special characters. Thus far I am pretty impressed after having worked my way through a good portion of "Q for Mortals".
My current "client base" is mainly interested in out-of-the-box lamp/ror/foss which has thus far held me back from introducing it into current projects. However I have a client who is currently trying to use php/mssql for really complex and massive historical data analysis and Q/KDB more accurately fit the job description so we'll see what happens.
Sorry if you were hoping for someone w/ more real world experience!
