Here’s one potential solution which wouldn’t require much to implement: Discuss: I found a smooth looking Discourse Blog theme, should we convert our Wordpress Magazine to it?
My other thinking is that we have a fantastic unique system where users can comment on and discuss any paragraph they click on (Docuss) and it would be a huge shame not to use it.
Docuss can be installed in WordPress and is automatically installed in a Reactjs solution. That makes these two the preferred options over the Discourse plug-in I suggested above
