>are we building the world we all want?

the rich are building the world they all want. everyone else is struggling to survive that world. so, no. we aren't building the world "we all want" because many of us want different things, and have different means to gain them. i'll note that facebook isn't intentionally blocking or supporting this dynamic... and i'll also note that they could have answered their own question by looking at their data set. but this is public relations, where facts are slim and the opinion of the actual public doesn't much matter.

>How do we help people build supportive communities that strengthen traditional institutions in a world where membership in these institutions is declining?

non-starter; facebook is anathema to traditional institutions because it localizes power within itself instead of relying on them... and this has been the goal of facebook all along. put differently: honest answers to this question cannot include facebook as part of the solution without actively subverting the "traditional institutions". furthermore, in the US at least, the institutions are hollowed out anyway.

>How do we help people build a safe community that prevents harm, helps during crises and rebuilds afterwards in a world where anyone across the world can affect us?

also a non-starter; facebook is a social network and software platform, not an army of robotic guards. "preventing harm" will be conflated with "enforcing stability" when they are prompted by groups with more power (governments).

>How do we help people build an informed community that exposes us to new ideas and builds common understanding in a world where every person has a voice?

don't let people use facebook unless they have a college degree or higher. you'll see university classes fill suddenly. more seriously: facebook is a filter bubble by design, and cares absolutely nothing about the reach of people's voices... and it's tiring to hear otherwise.

>How do we help people build a civically-engaged community in a world where participation in voting sometimes includes less than half our population?

by doing something that facebook won't do: taking a stand and promoting groups pushing social change forward. they already know that this is a line they won't ever cross. we all know that they won't cross that line. facebook is a large institution, which by default sides with other large established powers rather than the public. i will also note that "civic engagement" is a dogwhistle for the disempowered members of the public doing something to improve their own standing, typically in opposition to (and rarely, in cooperation with) the established powers. they don't even genuinely want to improve civic engagement, because civic engagement leads to them being obsolete.

>How do we help people build an inclusive community that reflects our collective values and common humanity from local to global levels, spanning cultures, nations and regions in a world with few examples of global communities?

what if we don't have common values, and what if we don't want inclusive communities? what if those of us who follow the western liberal tradition want nothing to do with those who live in contradiction to it and despise it? some cultural chasms can't be rectified... and i can definitively say that facebook won't change that.

in summary: leaving the construction of a global community to facebook is a surefire way to make sure that the "global community" is neutered and ripe for profit extraction. i guess this comes off as a very negative post, but come on-- think about who benefits if people worldwide jump on the zuck train and think about things in the way he's encouraging here. does anyone really think that facebook is actually interested in doing anything other than making money?
