This. And, as you mention, any comment system needs to promote thoughtful, quiet conversation rather than bombardment of reactionary blurbing.
I’ve found it fascinating since my brain injury in 2002 how I shifted my understanding of email, without realizing it at first. Others with brain injury interact in support groups via email with very thoughtful dialogue, but folks I email outside that community use email mostly as “FYI,” not to be interacted with. As Facebook increased in pupularity, email support group participation dropped rapidly, except for a few who needed the simplicity of email.
I’m not sure what this says other than the platform can be well designed for thoughtful interaction yet it also requires people chooseing to interact well and may not know or remember how until they discover it. How to promote that discover, of the art of conversation?
