There’s an art to asking questions. Some people ask questions about things they want to know, and it’s important to know. Some people ask questions to start a discussion or to be funny. Some people ask questions just to ask questions. And some people take care to crafting their questions to allow people the most openness in replying.
Bad questions (those that are unclear due to fractured English or insufficient detail) should be flagged, so the person can have a chance to explain what they are after. Good questions should be rewarded, although in the past, people have often overlooked that. It’s surprising when some says, “this is a really good question,” and the question has no GQs. Of course, that happens with answers, too. So it goes.
