BrianKrebsI'm pretty sure Mastodon is the first social network I've been on that didn't immediately ask me to betray all of the people in my address book.
I mean, think about this for just a sec: LinkedIn, Twitter, SnapChat, Instagram, the list goes on and on. The VERY first thing these platforms will do after you've installed the app and logged in is to ask you to share all of the information in your address book. Ever wonder how these social networks got so big so fast? It's remarkable how much of their growth is based on convincing everyone it's totally fine and normal to give away all of the contact information given to them by friends, family and acquaintances.
2xfo@briankrebs I shared my contact details with LinkedIn once because I didn't realize they had scrapped that from me somehow and those people weren't already on the service. I felt pretty used when I realized it sent them invites on my behalf.
I never allowed a service to do that again. I care about the privacy of my contacts as much as my own. (I mean, I guess it's still my privacy too.)
