I dont know a huge amount about blogs but I would say that you you should but something in your posts to get readers involved. For example ask them a question, ask their opinions, or anything that would make them want to post. Also make sure you are getting a decent amount of visitors to your site.
Thanks I installed Comment Love on my Blog. It is a pretty good plug-in.
Thanks, for the tips everyone!
I guest finding a way to connect/"Be friend" with my readers might also add more comments since some people are more likely to comment on online friends blogs vs a strangers blog.
Asking questions is a good way, as BamBam said, but it also helps to find dofollow forums of the same theme as your blog, and post responses to people asking direct questions about the content that is in your blog (with your link in your siggy). I've found this attracts readers who are actually interested in your content and not just in getting a linkback.
