I really like the “this post is super long” draft hint, though. I think that could be a new reminder type we pop-up when the user has spent (x) amount of time composing a post and the word length is over (y)?
It might be a hint that gets ignored a lot because of the sunk cost fallacy though. Once someone has dumped 5,000+ words into a reply, are they really going to decide to make it half the size just because we popped up an education panel after they’ve already written the thing?
I suppose if we treat it as a “just in time” warning, like …
It looks like you’ve typed 4,781 words in 35 minutes. That’s a lot for everyone to read! Can it be summarized? Should this be posted now to get feedback before writing more?
… then the take is “good work, make it as short as you can and submit it now before it gets too long?”
