Yeah the comments and interaction are the glue of the community. Sadly, it's something we don't see more of. Part of it is the lack of incentive and obsession with post creation for rewards. That explains the lack of comments on posts in general.
But on posts with a lot of comments, it's hard to get a discussion going. Comments tend to get lost and drowned out with the current format. The ChainBB interface does help with that imo and it's something i recommend for anyone looking to start a discussion.
It took me a minute to wrap my head around ChainBB. My initial response was "Ugh, what an ugly ui." Which, as I recall, was my first response to 4chan, (many many shameful ages ago), and subsequently reddit.
But dat functionality, doe! @jesta makes some ugly babies on the outside, but he(?) knows how to make shit work. Color me convinced.
