At the bottom of a blog post, article or page on a website the author or webmaster may wish to facilitate discussion between readers about the content. This is most often done using comments at the bottom of the post which usually take the form of a series of unstructured text replies which can be entered into a box provided, usually as well as name, and other optional information about the poster.
These comments will mostly be directed at the article and users post anything from just a word of thanks to a long form view on the content provided. Encouraging readers to comment and sparking a debate in the comments section at the end of posts is a powerful tool used by bloggers (and Internet marketers) to keep posts alive and encourage, sharing and debate across a wider audience than just the core readers of the site.
