Notifications are also more reddit-ish, only pinging the direct parent post/reply author, without bothering the whole thread, and people can go back to the thread for updates.
Navigation of comments is also better. So it’s easier to just post a simple joke, a quick comment, etc, and not accidentally annoy 50 different people.
And like reddit the post is treated as part of a community instead of a specific person’s timeline, which extends to how comments are treated too.
