Blogger is having some changes. The first change was appeared in last year by totally re-assembling Blogger appearance. The latest change to Blogger’s features has just been Announced, bringing threaded commenting to the Google-powered blogs. Google has been a little late to the game bringing this standard feature to its blogs.

Blogger now supports threaded commenting, which means that it is now much easier to differentiate between whether someone is making a general comment on the thread, or responding to another comment on the thread. Most of bloggers, including us are using different ways such as Disqus for enabling threaded comments but now it has been resolved. So you can now commenting in blogger as a "comment" or "comment to comment".
