@tomw I'm a nerd about hosting my servers and using open source software, but I shock people around me when I tell them that I ain't got Instagram, Facebook, Twitter or whatever mainstream social networks you can name. I do have LinkedIn, but only to have a public profile that people can search.
My smartphone is also stripped to the bearbones minimum of what I need to live in a digital society.
And it's exactly because I'm an IT guy and I know what's shady, that I stay away from it.
