Oh wow, the argument was not expected but also very compelling, I'd been wanting to quit commenting as it's a big waste of time and often leaves me sour, as you almost always comment in disagreement or engage in tough debates and so on. It rarely feels good.

But seeing it as a bad ROI in terms of social interactions that don't create any social bond, that's quite true. You spend all this time "socializing", and yet gain no social connection from it.
