GN is at it is. It changes along with the mix of posters. The dynamics constantly ebb and flow. It's a forum for all ideas, thoughts and feelings for those who wish to engage with it.
For those who find it rather bland, or too nice, then throw in a challenge or two for a robust debate. Engage others with new ideas. If not then there's a gentle ride.
A good debate is a way of hearing many points of view which I find can be illuminating in checking my own stance on any given subject.
Kindness, intellectual rigor, compassion, defensiveness and cranky/crabby moments are all here - plenty to choose from as and when.
