I saw something interesting for the first time. Might be a sign of things to come: I was reading an article: http://www.gottabemobile.com/2011/02/08/dell-latitude-xt3-convertible-tablet-pc-on-video/ and I noticed they had Comments - for signed in Users (can use Disqus, Facebook, Twitter, and OpenID to sign in). below the Comments there was a section for Reactions - These were From Twitter via BackType. When I click on back type it takes me to Backtweets.com. Anyone have "Reactions" on their articles ?
