Want comment form under posting on main blog page

It’s not obvious to blog visitors how to post a comment–and I would like it to be. Did I do something wrong–or do I need to do something special?

When someone comes to the blog, they come to the main page where they see all the posts. The only way to post a comment is to click on “no comments”. I would like this page to display the comment form or reply form. How can I do this? I’m not wed to a particular approach.
