It appears that the "statistically invisible" commenter is at the forefront of your thoughts, to an extent where you feel the need to address her/him specifically. "Many people vote with their time and attention." . Of course. We could argue that you have voted with your comment. The "statistically invisible" commenter got your time and attention (=vote). "Facebook measures how people behave, not what pundits say." There is a saying that goes something like, "What you measure you can control." It follows that what the "pundits" posit outside of Facebook is not something Facebook can control. Its simple. Users and non-users will stop publishing comments about Facebook when Facebook loses popularity.
