Stalking Your Friends with Facebook Messenger
Aran Khanna

Great case study! I’ve been aware of this default for awhile, and have been surprised at how many friends share their location with me without knowingly doing so. I think you are right about the UI, and Facebook should make more of an effort to educate the user on this — I guess it’s in their DNA, and Mark has tried to be more privacy centric, but it’s another failed example of why Facebook doesn’t think about this before they launch.
