Calling a meeting is almost always the worst way to accomplish something.<p>IMO it should only be done when you need to make an announcement or poll feedback from a group of people you don't usually interact with or who are busy.<p>If you have a question for a specific person, don't call a meeting; just use the easiest channel to contact that person and publish the answer.<p>If you need help with something business critical, don't call a meeting; do enough research to formulate an intelligent question and ask that question.<p>If you need to learn about something but it's not urgent, or even if it is urgent but not for anyone else, find the best person to learn from and ask them for a 1 on 1 at their most convenient time.
