If WordPress.com hosts your site, you can tap one more set of useful statistics. Take
a look in the Comments box to see which of your visitors left the greatest number
of comments and which posts stirred the most conversation.
The most interesting information is the top commenters. These people are particularly
valuable, because their input can start discussions and keep the conversation going.
Once you identify your top commenters in the past week or month, you can try to
strengthen your (and therefore your site’s) relationship with them. Make an extra
effort to reply to their comments and questions, and consider making a visit to their
blog, and commenting on their posts. If they stick around, you might even offer them
the chance to write a guest post for your site, or to become a contributor.
