I can't speak for the others, but on my part, I've noticed on several occasions a chance for proper discussion, yet I've refrained from even properly starting because the moment you say something enough people might disagree about is the moment you heavily risk getting downvoted - and often if there's substance for a proper discussion, there's also room for disagreement because otherwise there wouldn't necessarily be much to really discuss about. Why would I invest in a proper comment when it has a high risk of getting downvoted to oblivion? That, and articles get buried quickly enough for discussions to get buried as well, and I feel the tree structure of the comment sections also helps bury discussions. For a proper discussion, a traditional forum thread is more suitable due to its greater persistence even without the downvotes, but I can personally say that the downvotes don't help either.
In a way, comment sections feel like Twitter: They're suitable for witty and likeable comments that don't go to any great depth, but they're a poor forum for proper discussions.
Bolded, very well put and it mirrors my own opinion of the comment section of articles. Lord knows if there is enough meat for a discussion someone should be creating a thread. For the record I liked your comment and still replied take that @Ryuu96.
Thanks for sharing what sometimes keeps you from posting. I can see that point of view and motivation or lack there of for posting.
I really like the articles and appreciate the effort that goes into them, the real draw for me personally is the discussion in threads. Although I don't spend the time here I once did I still very much appreciate the site and it's users.
