Comment on Social Media Marketing Tips by Mark.
Maybe the answer is continue to make a blog function somewhat like a forum or social network. With recent comments, avatars etc. I think Prelovac has a comment plug-in that makes comments as pages. I think some of the success of your blogs is people keep coming back to comment.
I am looking how to also take this a step further.
Sorry for using your template page to think out-loud on this.
