@pfefferle I think there's a bit of a push to provide a full fediverse client (that includes two-way interaction between users). That's what the NodeBB integration is trying to do — to be that all-in-one fediverse client.
But the reality is there's no reason you have to do that. Simply federating content out and maybe ingesting responses back as comments would be a feature complete integration as far as I'm concerned! Anything else is gravy.
