Thinking about protecting personal information in everyday life, I find the smaller practical questions more interesting than a quick conclusion. An unexpected request for personal information is a good reason to pause and check who is asking. For Chronswojedane, I would use personal data protection as a starting point for a closer discussion of the subject. I am still thinking through the practical side, because the context can change what seems useful. What would help someone decide which information is genuinely necessary to share?
