First Time Looking Into Twitter Analytics

Well, this was my first time ever looking into Twitter Analytics (I might have when I first signed up back in October 2009).  It is quite interesting.  The Tweets that have the best impressions and engagement is quite interesting because it was more "on the fly" Tweets than actual prepared Tweets like the Tweets that are promoting my website.  Which on my behind the scene analytics of this website, I get the majority of my hits from Twitter and not much anywhere else.  So, I guess I'm going to be using Twitter???
