Darren Rowse knows that bloggers want communication, that is why most of us start blogs. We may think comments are not important, but we like our work, our effort to be validated in some way, even if it does nothing more than start an argument, as that is some form of conversation and so he has taken it upon himself to list ten techniques that you can use to get people to comment more on your blogs.
The first four in the list are some of my favorite methods, and they include:
1. Invite Comments
2. Ask Questions
3. Be Open Ended
4. Interact with comments left
