Tree nested communication is much more superior than traditional thread based communication
Heavily depends, IMO.
Nested threads are great temporary discussion of a specific story or idea. They’re absolutely miserable for long-running discussions. New posts get lost in the tree and information ends up scattered across multiple threads as a result.
It’s also been my personal experience that the nested threads format just doesn’t seem to build communities in the same way forums did. I have real-life friendships that were made on forums decades ago and I never had that experience with reddit despite being a very early user.
I don’t think that’s entirely due to the ephemeral format, but I do think it plays a part in it. A deep thread between two people on Reddit might last a few hours and a dozen replies before it falls off the page. On forums threads running months or years were pretty common, and that kind of engagement with the same people certainly changes how your relationships develop with them.
