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.
And as a contrary case, I liked this post with no 'real' reply because I found the comment good but had nothing to add. I think liking without posting is fine, but I can definitely see the potential problem there as well.
