A few weeks ago, we announced a couple features that were being exclusively previewed on Mashable.com. We posted:

We’re big believers in the power of the comments to overtake the blog post. Content may be king, but with a great audience, it is only the first voice in the conversation to follow.

We were introducing Social Media Reactions, a new feature on Disqus that aims to connect the discussion on your site with the scattered conversations occurring everywhere else on the web. Today, people have many tools available to discover, read, and discuss great content. Blog posts and articles can be mentioned on Twitter, commented about on Digg, and even shared across FriendFeed. Now, these social media reactions can be connected back to your site keeping the conversation together. When your posts are being discussed on Twitter and Digg, these tweets and comments will appear within your Disqus powered comment thread. Here are two examples from inquisitr.com and avc.com (under the main comment thread).

Limited Release

Starting today, we are doing a limited release of this feature to sites on Disqus. By next week, every site on Disqus will begin seeing reactions on articles. But, you can enable it for your site immediately to be first in line. To enable this feature, head to your Admin/Settings and enable Social Media Reactions.

The full list of currently supported services include comments and entries from:

Twitter, FriendFeed, Digg, Blogger, WordPress, TypePad, Movable Type, YouTube, Vimeo, Picasa, and Flickr.

Thanks to our friends at uberVU, our new conversation tracker was possible. They’re doing incredibly cool things and we hope you check them out.

Tweet your comments!

We have one more bonus feature. Now, commenters can broadcast their comments out to Twitter with a link back to the post. By bringing the conversation to Twitter, people can let their friends know about interesting articles that they are discussing. For commenters with Disqus accounts, head to Account/Services to enter the necessary Twitter information. Here is a short video explaining how to setup and use tweetbacks.

We are focused on helping you keep the conversation together and bring out the best discussion on your sites; What do you think? Leave your reactions in the comments below. Or elsewhere — we should find them.
