Joe Edelman critiques privacy on Facebook as we actually experience it. The first point in particular is far too little commented upon, I think: you really don't have meaningful control over who your posts reach, because an algorithm decides that on your behalf.
Facebook is far from being a good place for people to live with privacy. Here are some things that might need to change:
- On News Feed, you don’t know who you’re talking to, until after you post.
- With new friends, or if a stranger is tagged in a post, there’s no easy way to scope out this new person.
- Your audience on Facebook tends to be an unusual, disconnected mass of friends, acquaintances and strangers.
- Unlike in real life, there's no way to know online whether someone has dropped everything and given you their full attention.
