This might be a silly question, but I'll take the chance to ask it anyway.
What constitutes personal data? More precisely, using FB as example, does it apply to things like:
1. where have you been?
2. what have you liked?
3. photos you've shared?
4. comments and posts you've made?
Or is it really just identification details like name, address, etc.?
