unless someone comes up with an alternative that everyone you know can get excited about, there will be no mass migration.
I’m not entirely sure that’s true. We may see a sagging, deflating of FB over time, lessening of social media throttleholds in general, and a fragmentation of available attention. People are getting sick of social media. They may not want to replace Facebook at all; they may want to reclaim their attention and their minds altogether.
This is beginning, with educated, well-off, and/or tech-savvy people leaving FB. It’ll likely trickle on down through the socioeconomic ranks. Right now, the biggest increase in smartphone market penetration here in the US is among lower-income users.
I’ve been off FB since late 2016 and could not be more satisfied with that decision. I can hardly believe people are still willing to go on the site, given everything we know. If any group I’m a part of insists on using FB I simply say I won’t be participating that way and I find another way to stay apprised of what’s happening. The idea that it’s not possible to leave these sites is propaganda and is frankly utter nonsense. I won’t trade my privacy and that of people I care about, and democracy, for the dubious benefits FB offers. BTW I don’t use any of the other social media sites either - I use Signal for messaging and protonmail for email.
