Just observed the new platform of commenting in my blogger blogs, I think it very easy and solve many troubles we have faced with the old platform. It is faster and allows you to directly leave you comment.
Otherwise the old one where you must leave the post page to leave your comment, you can easily add you comments without leaving the post. Enjoy the new commenting platform and say thanks for Blogger. Try it now here in this post to find out how easy it is.
How to convert to the easy comment platform:
Go to Settings >> Comments and find "Comment Form Placement", then choose "Embedded below post" and save your blog. Now go to any post to find the new comment window that allows you and your visitors to comment directly from the same page without going to a new page.
