Having followed MacRumors for 4+ years and being a member for about 18 months, I've noticed that the past few months have shown a sharp increase in the number of speculative replies. Should there be a community rule about answering informational questions with speculation? Something along the lines of, "Out of courtesy, please refrain from answering, in an authoritative manner, technical questions outside your fields of expertise. All opinions are welcome on MacRumors and discussion is encouraged where appropriate and/or invited, but in order to provide the best information with minimal clutter, please exercise discretion." There are times when MR discussion is a back and forth affair, like what will happen to the eMac or whether the black MacBook is a ripoff. Those are appropriate topics for discussion and opinion and ones with no one correct answer. On the other hand, factual questions like "can I use ACD brightness controls in Windows?" shouldn't have to devolve into arguments (that specific thread did not). Posters, at least in my mind, shouldn't post in a thread asking a specific question with a specific answer if they don't know the answer. Until recently, this didn't seem widespread. People replied to answerable questions with the answers, and everyone else read quietly and learned a thing or two (or confirmed what they already thought), with the occasional honest mistake. Maybe it's just me, but does this new trend seem problematic to anyone else?
