Comments
Comments are a way for visitors to add feedback to your posts and pages. If you choose to enable comments for your posts, then a comment form will appear at the bottom of the posts and people can respond to what you have written.

Approved comments are displayed on the individual posts, not on the blog home page. Click on a post title to see comments. You can show the latest comments on the home page by adding the recent comments widget to the sidebar if you wish.
Comment Management
Blog owners are in complete control of the comments left on their blog. Users on the blog who have Editor or Administrator rights will have the ability to manage comments. You may also turn off comments if you don’t want to use them.
