1. social login icons have disappeared from the newest version...Why does this matter? If people see those icons they are 20 times more likely to post a comment...It's easy, simple, clean, and more trustworthy from your users point of view.
2. social login is now a FARCE...you still have to register for a Disqus account...disgusting...A big impediment to users commenting.
3. if you change your comment plugin later, your comments are GONE...that's a whole lot of faith.
4. last, and probably worst, it added 30 http requests and seriously slows down your website...this is one of the cornerstones of good seo/adwords/etc.; a fast loading website...And this plugin kills it...
They could clean all of these things up easily. If they do, I'll give it another try, because it does look nice.
