From cursory inspection, questions about and tagged as "matlab' get few if any replies. There are probably many users of MSE working (also) in matlab, so I can see how it was originally created. However, when I notice it in a question, my impulse is to want to refer it to another site, such as stackoverflow, both as it seems like a more natural home for it, and as the response here - if I'm not mistaken - is minimal. However, given the existence of such a tag, it is perfectly legitimate to keep it here. Is that what a majority of users believes should be the case? I have no strong feelings in the matter, but wouldn't referring such a question on be in the best interest of OP, and this site?
