Comments are a very important part of your blog. If you have a blog setup, you want to make sure you give your commenters a little something extra, to keep them coming back for more. Here are ten great comment plugins for the WordPress publishing engine.
- WP Grins – WP Grins will provide clickable smilies for both the post form in the admin interface and the comments form of your blog.
- Akismet – Akismet checks your comments against the Akismet web service to see if they look like spam or not.
- GD Star Rating – Star Rating plugin allows you to set up rating system for pages, posts and comments in your blog.
- AJAXed WordPress – A highly customizable plugin to add AJAX to your blog. AWP uses AJAX to load posts inline, paginate posts, load and submit comments, and more.
- MyCaptcha – Allows you to display a captcha on your comment form to avoid spam.
- Subscribe to Comments – Subscribe to Comments allows commenters on an entry to subscribe to e-mail notifications for subsequent comments.
- WP Wall – “Wall” widget that appears in your blog’s side bar. Readers can add a quick comment about the blog as a whole, and the comment will appear in the side.
- Live Comment Preview – Live Comment Preview is the simplest way to get live comment previews on your site. Simply activate the plugin — That’s it!
- Easy Gravatars – Add Gravatars to your comments without modifying any template files. Just activate, and you’re done!
- @ Reply – This plugin allows you to add Twitter-like @reply links to comments.
Know of another one? Leave a link to it (and let me know why you like it) in the comments!


Nice List!
I’ve another suggestion here http://wordpress.org/extend/plugins/newsgrape-sync/ that syncs the comments automatically from and to the article on the platform.
And why didn’t you include disqus?
