[Q4273j3b]

When a lot of my friends say "privacy" they really mean: "the barriers I put up around my content, which is of course online".

Then there's "privacy" in the sense of being a private person: you don't want your photos and conversations widely seen or read in the first place.

If Facebook and all the other data brokers could choose one of these definitions of "privacy" to lodge foremost in your brain, which would they pick?

Which definition would you call industrial, and which one cultural?

It sounds like you're just a private person, ancarda. By all means, carry on.
