StylizedWeb has an interesting post up on increasing the number of comments on your posts. It covers a lot of ground, and has some tips worth trying.
Engaging Readers, Design Your Way to More Blog Comments
First the post explains why people comment, and then moves on cover some theory and tips on how to maximize commenting by providing more incentive.
The primary reason anyone is going to leave a comment on a blog is they believe that their will be some pay off that is worth their time to formulate their response, edit it, etc… In most cases it is because they have a feeling about the content to the point where they feel the need to get their thoughts off of their chest, or maybe the author is well known enough where the idea of talking with them would be the reward.
