The popular alternative commenting systems are:
1. Intense Debate –
I find my old commenting system dull, so I changed it using intense debate commenting system on this post.This is now owned by Automattic, the makers of Wordpress.
When you try to revert to any of these commenting systems,make sure that you backup your template and keep a copy,so that you can revert back if it didn’t work out well.
These are the three most popular commenting systems.They come with threaded commenting with Gravatar based profile images,which can make you commenting system look more professional.
So if you want to remove the default blogger commenting system and get a better commenting interface,then you can opt for any of these commenting systems.
