It definitely started years ago, probably around the time I really started using it. I visit /r/games sometimes and they have stickies around what you have been playing or game suggestions and without fail someone doesn't even read the topic at hand and just posts a random question. Apps were mostly bad at showing sidebars too, they wanted to streamline the main view. They were there but I think a lot of users didn't know. Anecdotally I seem to notice a trend on how grammatical/spelling corrections are received. If people generally accept them in good grace as a chance to improve, discussion quality can be decent. If they take it as a personal attack, or other people pile on (often with the classic "no one cares") ... well that's Reddit these days usually.
