You're getting downvoted, but I think low text density contributes to the low quality of conversation. I've commonly witnessed conversations that were going around in circles, with people just tuning in and re-asking questions that were already asked and answered in the same conversation two or three page scrolls up.
If it's not on the bottom screenful of text in a channel it might as well not exist on Discord. Which is funny, because one thing that people really like to bring up when comparing IRC to Discord is its lack of persistent history. It turns it doesn't make much practical difference.
