I'm starting this discussion to share the best sources of quality information to learn about privacy and security.
I think it's important to do this to offer better community advice.
I'll edit this thread over time: I'll add the best suggestions, remove misleading and poor quality sources. I want it to be community knowledge, so share yours.
For now, I will based it on BeerIsGood guides.
