That is bc Reddit used to be a discussion forum, but along the way (to the planned IPO) switched to aim to become a social media platform. Longer comments literally got harder to type out, as more users were pushed towards using the mobile app (to monetize their data?), which in turn brought in a younger crowd, used to different forms of interactions from other social media sites. I've heard reports of old-Reddit starting to break after July, and you just know they'll kill it off entirely soon enough, or would if they thought they could get away with it.

Reddit literally changed, lead in large part by the push for the IPO, and it got harder and harder to buck the trend.

Until we all just gave up on it entirely and came here instead - problem solved! :-P
