Disqus is going to launch two features to help blog readers track the most interesting comments on a blog or other web site.
Forum and blogging software has been around for many years, but there’s still no easy way to find the best comments within a web site or from across web sites.
Disqus has a two-part answer to this problem. It provides an advanced commenting system that can be added to a blog article page. Features include nested comments — tiered according to the order in which they were left — and a way for readers to vote for or against comments, and spam protection.
The other feature is a forum hosted separately by Disqus that displays comments from a blog according to how recent the post was published and how “hot” the discussion is on a particular post — in other words, how many comments that post has.
