Re: Facebook is tracking you.
Also speaking as a thankfully-retired IT security manager, the sad thing is that any use of the internet results in lack of privacy, not just Faceache and Twatter. Microsoft, Apple, Yahoo, Google, and just about every on-line retailer collect data on your likes and preferences. You have two options. Cut yourself off from all communications, or else just be careful what you do. It's a fact of modern life, unfortunately.
Just take it easy. There's always tomorrow. And if tomorrow doesn't come, you won't have wasted any effort on it.
