I use Zurker!
Zurker is a revolutionary type of social media that is owned by its members. It's open, transparent and democratic.
There are no adverts and spam is strictly controlled.
You can easily control your data and privacy and on your own terms.
Zurker is still small; about 90,000 members worldwide but it's growing fast, probably about 100,000 members by the time you read this! To be serious, growth has averaged about 7,000 per day over the last week.
Zurker is still in beta so it is a little bit clunky in places, but robust and fast.
I've written a fuller hub about Zurker if you want to know more.
