I much, much, much prefer the original, threaded and immutable conversational structure of traditional forums.

One thing I particularly despise about reddit is having to scroll past the bevy of meme/joke/tired reference (is that a jojo reference?? unexpected letterkenny!!!) comments that percolate to the top thanks to upvotes. In reasonably popular subreddits anyway, more niche ones may not generate any comments at all.

I'd much rather find a megathread about a subject on some popular forum, start some time in the past and work my way through the posts in chronological order as god intended.
