I was using Disqus comments on this blog but i was not satisfied with it. Reasons being, it was increasing load times and sometimes inserting ads, even after opting out and expensive. And there is privacy issue with it. To enable Disqus, all you have to do was signup and add site tag in config.toml/config.yaml. But i decided to let go and go with giscus.
What is giscus giscus premise is simple.
