I understand what the author is getting at. I myself have read links about new tools and frameworks and might think afterward, "that's pretty cool". Then I'll read the comments section where often I might fall into the trap of hoping others share the same opinion and maybe feel a little hurt and offended when those hopes are dashed. That is simply the nature of any social media platform. And it's probably healthier to let the comments section act as an additional resource on the topic, and one that might challenge our own way of thinking. In this way, comments are not agents of decline in our critical thinking. They are instead, part of its growth process, providing us with differing perspectives that should themselves be evaluated on their own merits and incorporated into our own thinking about the original topic.

I myself can't imagine this site without the comments, especially for additional links that are often provided relevant to the post. They are a great place to deepen one's own investigation of an interesting topic. And I've often been led to other parts unknown to me when reading them.
