This is not a community concerned with upvotes. It is a community concerned with content, and especially with getting good content as quickly and as easily as possible. We upvote to signal good content. We do not comment to signal good content; that is what upvoting is for. We comment to add content; this can be in the form of insight, correction, elaboration, humor, summarizing a long article well, adding a personal anecdote or expert knowledge, answering a question, or any number of other things. Our comments should not be complaints, memes, or other wastes of space and time.

Before clicking the reply button, ask yourself, "Am I really adding something, or should I stop procrastinating and get back to work?"
