I leave a leave a response whenever I appreciate a article on a blog or I have something to add to the discussion. It is caused by the sincerness displayed in the post I read.
And on this post RELIC-SIGHTED. I was actually excited enough to drop a comment

I do have a couple of questions for you if you tend not to mind. Could it be just me or does it seem like a few of these comments appear like left by brain dead individuals? :-P And, if you are posting at additional social sites, I'd like to follow everything fresh you have to post.
Could you make a list all of your public pages like your Facebook page, twitter feed, or linkedin profile?
