I'll tell you what someone should have told Zuck.
You need to separate out the permissions for synchronous communication and async since we already build an "alternative twitter" in the 2000s -- it was called... SMS.
What you are going to need to do is VERY CLEARLY distinguish what is permission for lack of a better phrasing... "broadcast" from permission for synchronous comms, because those are two VERY different things, both in a social sense and in an IT sense.
(You do know what peer to peer means... right?)
I signed up for Facebook, and to me it was like "*Wait... do these goddamn pedophiles not know some of us went to computer camp?"
The air of entitlement off the folks I spidered off from that network of Harvard people was... intense.
For context, after Columbine, the school I was in told us how to dial out (9, then 911) and in parallel, told us if we wanted we could apply to the township police.
I didn't have the same ability to express myself back then, so I wasn't able to articulate what I will today, in a less threatening way:
Why the fuck would I call the police if someone shot my teachers? They abuse me. They smirk that they think it's funny because we have less money, we only get to sue them if it's a test case with the ACLU.
Right as I was getting to a point I could put it that simply, 9/11 happened, and it felt like they took those... techniques... and deployed them on the rest of the world. Which sucked, since back in 412, up until the Iraq war you could pump gas then go into the station to pay for it.
(They'd take down your plate if you drove off.)
Anyways, please include a voice chat option in your network... I am on the autistic spectrum, but I've gotten a lot better at spotting when someone is a literally a spy and voice gives a lot of information.
(Or you could skip all of the above, and focus on why people seem to need to move from network to network, when it feels like in a comedy context, we've known what's OK for a very long time?)
