It sounds like you may be wanting a Question - Answer app more than an app for Discussion.
eg. title: “What is the best Ember based forum app?”
post content: n/a
vs.
title: “What is the best Ember based forum app?”
post content: “I am looking for a forum app that runs more like a desktop app than a traditional forum experience. My shop knows Ember well so I am leaning more towards Ember. Free would be ideal. Anyone have suggestions and why? TIA”
Which would be more likely to encourage a discussion? Which would be more likely to get meaningful replies?
Granted, I don’t know your community, just saying if you truly need no content posts you may want to give your choice of platform some thought.
