Disqus is a service for web comments and discussions. The Disqus plugin makes commenting easier and more interactive, while connecting websites and commenter’s across a thriving discussion community. The Disqus for WordPress plugin seamlessly integrates using the Disqus API and by syncing with WordPress comments.
Comments are resource intensive. If you have a lot of comments on a post, then it will take a long time to load. If a lot of users are leaving comments at the same time, then it would also impact your server load. The advantage of using a third-party commenting system like Disqus is that you shave that server load off from yours and send it their way. Even if your site is getting attacked by a malicious user, it won’t impact your server because it has to go through Disqus first.
You can always revert back if you don’t like the platform because it syncs with your WordPress database. If you’re running a fairly large site across multiple servers, then having a third-party commenting system helps with redundancy. You don’t have to worry about syncing comments because they are not tied to your database. Disqus comments are connected with the URL of the post or page.
Adding Disqus commenting system to WordPress is fairly easy. The first thing you need to do is go to Disqus website and Sign Up for a new account.
