In this post on meta, I suggested that
programming-related questions should be on topic, provided that they require some amount of OR-related expertise
and implied that questions about, say, connecting to a solver's API, solver installation issues, or importing data from SQL to a modeling language should be off-topic, even if they relate to OR software like GAMS, PuLP, or COIN-OR.
So I'm revisiting this question: Should questions about OR software be on-topic, even if they are not actually OR questions?
An argument in favor of considering such questions on-topic is that the people who design and use OR software packages are (we hope) going to be hanging out at OR.SE, so this will be the easiest and most natural place to connect askers with answerers.
An argument against is that these could be considered programming questions, not OR questions, and should therefore find a home on Stack Overflow instead.
