You go to espn.com and comment on a sports story. You call the Lions "perpetual underachievers" in a comment. Facebook now knows where you were, when, and what you said. They use this information to cater the things that are presented to you when you are at Facebook (not being active there, you're simply not too affected by this; but remain aware that the gold all advertisers seek is **your attention**) AND they sell that information to advertisers.
OR...
You go to some-lingerie-site.com to check out something for the Mrs. At some product pages there are reviews, which use the Facebook API. You do not use any of those functions, HOWEVER, Facebook still knows you were there, for how long, what pages you viewed, etc. and uses that very valuable information accordingly.
For people who track you, YOU ARE the product. They sell your surfing and navigating habits, likes and dislikes, visit frequencies and who knows what else to market research companies and directly to advertisers.
Many people are also uncomfortable with anyone - commercial, gov't or anyone else - having that information about them. We may not be far off from you getting some unwanted attention because Facebook knew (and sold or surrendered that information) you'd been at some-gun-site.com a few times too many for someone's liking; or from a prospective employer forming a judgement about you because of the review for "50 Shades of Grey" you left at Amazon.
