I’m in the process of creating a new website, having Discourse as forums software. I plan to use the same approach you currently do:
I like the blog format you use now, thank you for your suggestions.
Wordpress 
There is a Discourse plugin which allows you to integrate the commenting (among other things).
Thank you, I was hoping it is Ghost for Docker or some Discourse plugin for Hugo.
I’m thinking to use Hugo and embed the Discourse comments. If anyone else have suggestions, please share them. Since we use Docker for Discourse, it could also make sense to use a dockerized Ghost? I like the Hugo simplicity and speed.
I use ghost + Discourse for my blog at blog.codinghorror.com so yes that can work too.
That is great @codinghorror, any advice you have for Ghost integration with Discourse? I plan to use a multiple container configuration with Docker-CE.
