Hi, I didn’t notice that you linked my site 
https://monocycle.info/ is indeed linked to Discourse with a few custom things:
- The right sidebar shows the last created topics, through a custom (and badly coded) Wordpress plugin. The list is updated regularly with a CRON task.
- The comments are sync between Wordpress and Discourse through a custom plugin that extends WP-Discourse. Logged in users can post comments either from Discourse or directly from the Wordpress article page.
@frold coincidentally, we use the same Wordpress theme
