So Drupal has a 'special' commenting system.
Comments are second-class citizens in Drupal compared to nodes...
But why did the core team not just create a default Content Type, Block and View for comments, and allow the site administrator add in a comment block as necessary? Just like the 'Article' and 'Basic Page' content types, which we can create blocks and views for. Why are comments so different?
UPDATE This question has technically been asked before, but for anyone new to Drupal (like I am), they might not have the correct terminology to ask the right question. And so I am leaving this question as is.
