Today when a periodical asks its readers a question, it does so in order to collect opinions on some subject about which everyone has an opinion already; there is not much likelihood of learning anything new. In the eighteenth century, editors preferred to question the public on problems that did not yet have solutions. I don't know whether or not that practice was more effective; it was unquestionably more entertaining.
In any event, in line with this custom, in November 1784 a German periodical, Berlinische Monatschrift published a response to the question: Was ist Aufklärung ? And the respondent was Kant.
