About a day or so ago Disqus released a slight, but noticeable change to their new profiles feature in Disqus 2012. In addition to the profiles feature displaying comments, followers, and who the person is following, the new profile will also show how many up-votes (or likes) a user has.
Other than that, there hasn't been many other changes to the latest version of Disqus. I personally wish that the new profiles display in Disqus 2012 would still display a user's popular sites, much like the classic Disqus does. For comparison, visit disqus.com/(username) to see the new profile display, and visit disqus.com/embed/u/(username) to see the old profile display from the classic Disqus.
