I think the comment system has to be simplified by removing p/c comments and adding option comments at the bottom of the option page. Like this: http://i.imgur.com/24XAi3O.png
I understand the reasoning for comments being the way they are now and I even prefer it in terms of neatly organizing everything in its appropriate place, but it creates roadblocks for community building.
The comments are always an extra click away. Meaning that discussions get buried, notifications get buried and reading all option comments requires a lot of clicking and waiting on pages to load.
It’s hard to start a discussion the way comments are set up now.
On the other hand having a single comments section at the bottom of the option page would allow smoothly transitioning from the structured information to a more free form exchange of opinions. It would help create a sense community and allow for an easy way to engage. In a way that’s intuitive and super-simple.
