Discord is also at least 2 completely different experiences IME. If you're in a niche server, it can sort of work like reddit with threads etc, because there's like one reply every 30 minutes to a day or 3.

If you're in a busy community it's clearly not at all like reddit, and is like all the huge chat rooms of the past and range from immediate interaction time waster to completely unusable for anything except watching text fly by.
