Disqus is a best rated commenting system,by me.As we use Disqus,I know well that Disqus have some amazing commenting features that others didn't provided yet.I'm using Blogger,as a platform and the comment box they provided is customizable but,not well defined or organized.
As I rated it 5 star,though I got some solid reasons to prove it,possibly after reading this post many of readers may change their commenting system.
Say no to SPAM
Let you make money through comments
