I’ve never been much of a Facebook user (just a few family things) and stopped using Twitter last year – they are just too frustrating and aggravating, filled with snark and hate. No matter who you follow it always finds a way in.
The only “social” space I inhabit now is micro.blog because it is more a blogging platform with a social layer (almost like a commenting system) that promotes and encourages ownership using indieweb principles.
The backlash is growing but I fear it will never be strong enough to actually hurt the networks and cause them to truly rethink how they operate. But as long as it continues to grow, even just a little, there will be enough to support the open web and prevent its demise.
