"Every click you ever make is recorded by Google." "Facebook is harvesting all your data and selling it to companies." I always hear comments like that. I'm supposed to be scaaaaaaaaared. And I don't know what to think of all this Social Media / Big Data / NSA / etc. fearmongering because I don't have a good understanding of web technology, privacy laws, etc. From what I would suspect, if some analytics team determines that people like me, who read the Drudge Report, are 32% more likely to buy gold ETFs, they're just doing a number crunch on anonymized data sets. It's not like my name and SS # and pictures of me funneling beer are being used. There's also something that my parents say that I'm almost certain is completely wrong. They say that employers doing background checks can see all your Facebook activity regardless of how your privacy settings are set. Obviously that's not true unless the company running background checks has a team of hackers or if Facebook is handing over to them my profile. I'm not sure where these myths originate. Anyways, can someone give me a primer on internet privacy?
