A few years ago, I was doing one-on-one tutorials for a series of consultants to introduce them to the blogosphere.  I told them blogging stands on a three-legged stool: posting, linking, and commenting.  In order to be successful, you need to do all three because a blog (personal or professional) is not your opportunity to push “send” on your opinions to the world, it’s a conversation.  The idea is to generate an intellectual, perhaps sometimes spirited, discussion on a topic that a number of folks can benefit from by adding their point-of-view.The A-list bloggers still have a lot of conversation going on at their blogs, but I’ve realized many of us not in the A-list league have simply moved blog conversations to other social settings: facebook, friendfeed, and twitter.  I’m wondering if that is a mistake.  By commenting on a blog, you leave a thoughtful response to the author’s post in a place where it logically belongs.  Fragmenting conversations off onto other platforms dilutes some of the value of the “conversation” effect.  I’m guilty of this as well, and thought I’d make a more concerted effort to comment on blog posts I value.  Unless you throw in with the “blogging is dead” crowd, I urge you to step up the commenting as well.Just sharing.
