Many bloggers want more comments and readers, this post will help you increase your comments if you feel your blog is really good..

1. Show Top Commentators: This is the best plugin for adding link love to your commentators, it displays the number of comments by an user and the website of his, you can reset the count weekly, daily, monthly etc.
2. Brian’s Threaded Comments: This plugin adds a ‘Reply to this comment’ link to every comment. When you use the reply link, your comment is placed directly under the comment you replied to. This plugin helps increase comments, makes it easy for people to reply to comments and prevents readers from scrolling down to look for answers to their questions. Many (good) blogs use this, even I use it
3. Subscribe to Comments: This plugin allows commenters on your blog to check a box before commenting and get e-mail notification of further comments. This encourages readers to come back and take part in the conversation.
4. Comment relish: This plugin sends a thank-you email to your blog’s first time commentators. This encourages them to come back again and comment regularly.
5. Link Love: This plugin turns off nofollow for all commenters who have made at least 10 comments. The number of comments is configurable by changing a variable in the plugin.

More to be added soon, or you all can also contribute by commenting
