Professional bloggers are saying more and more that comments on a blog post are as viral a search engine optimization tool as linking and any number of other tricks. I don't know if that's true or not, but I really like that the Blog Book Tours blog-a-day challenge has resulted in lots of conversations between the participants on their respective blogs. We're also getting commenters from Twitter. Comments seem to make the post live longer than without.
Blogs like The Lipstick Chronicles become favorites as much for the comments as for the original posts, so it's a worthy goal. I've lately been analyzing why blogs get commentary. Personable writers, controversial themes, pertinent questions, great information, good writing, and even contests are all techniques for inspiring reader participation. What's your favorite technique to inspire interaction? Have you developed a technique yet? Think about what might work for you.
