I posted in the referenced thread when I was a real noob to SMF/TP and now I'm not so sure enabling comments to the article system is such a good thing.
I was thinking with my BLOG hat on and saw the potential of using the article systems for blog entries. Although I'm sure that potential is there, I'm now thinking (minimalistic) blogging could (should?) be done within the existing SMF system with changes to some sorting algorithms (chronlogical) and theme changes (show N messages more like BoardNews) instead of showing a page full of subjects only like a forum.
Most portals system that try to roll their own BLOG get flamed almost as bad as portal systems that try to roll their own forums.
Stay the course Bloc - do what you think is best for the article system.
