In my blog, comments are not supported, and it would be easy to add if I developed my own blog with Django. But I feel that this single feature does not overweight the simplicity and velocity I have with such setup.

If you really need comments in your blog when using Hugo, you can still integrate them with Disqus https://gohugo.io/content-management/comments/

In regards to the requirement to know Git: It is just necessary in the setup phase, the blog posts creation and edition are controlled through Netlify CMS for me.

Interesting, thank you for introducing me to Netlify CMS, didn't know about it.
