I feel like the comments sections in articles are a good place for having discussions. (I have never visited TV.com forums and am only doing so because I strongly feel about this thing of mine).
Anyway, I feel like the comments section can be easily "spammed" out by people essentially just saying stuff like "omgg soo awesome I loved it" which effectively throws earlier comments in the "load more comments" section: looked at by very few people.
I don't know what the ideal fix to this solution could be, but I feel like comments should definitely not be sorted by date added, but that maybe the liked comments should get priority so that comments that users like / have interesting points for discussion should remain on top of the comments so more and more users can see it & potentially join in the conversation. This "like" feature should also apply to sub-threads within the comments section, there should be a way to hide the non popular comments & only show the popular ones -- again to save space.
Now I know this would mean that new comments would just never be seen by anyone and so it would be hard for a new comment to stirrup a conversation. Possible fixes for this could be to A) Have a top comments section like youtube or B) give each new comment a grace period of 24 hours where it is added to the top of the comments stack (as it is now) after which if it doesn't get enough likes it drops down and gets sorted by # of likes.
