I have added the Disqus (pronounced discuss) comments and discussion service for more interaction with the site and other users.
One of the problems with implementing a comments/discussion section has always been the amount of spam. Disqus eliminates all that and allows open and spam free comments and discussion hosted on their network.
According to a study by Lijit, Disqus was used by 75% of websites in March 2011 who used a third-party commenting or discussion system. Disqus operates on the freemium financial model similar to Dropbox and Evernote. The service is free for commenters.
The Disqus comments/discussion module is at the bottom of every post.
