"How is Facebook changing our privacy habits for the good (or bad)?"

Facebook is starting to affect our privacy habits for the good, by making us interact with strangers more easily, not to mention be more open. We can speak with others more easily, and eventually learn about them.
However, facebook is beginning to affect our privacy habits for the bad, as sometimes we cross the 'line' when we share information with them. As when we learn about them, there's a good chance they learn about yourself.
The 'line' itself is hard to see, as sharing information with someone may not be all that bad, but depending on that information, it could also be very dangerous.
Sure, it's alright to speak to others about whatever subject, but it would be best to keep things vague, not naming certain individuals or places.

The subheading which I typed out, 'Targeting Your Likes", spoke about how Facebook is becoming better and better, how it works, and other information.

Facebook is becoming better and better by giving its user so many options. For example, it has a Like button on other websites (Facebook's logo is beside it to tell you it's for them) and if you were to click on it, the user would find it under their Facebook profile.
EX: If someone clicked it for the movie, 'Transformers", they'd find it under their Movies in their Facebook Profile, and not only that, they could share it with their friends/peers.
Not to mention, Facebook provides a social ground between users.

It explain how Facebook does what it does, with the support of other websites, and how something like their 'Like' button, or advertisements, provide them with data.
