You (gldalmaso) don't list your email address, but you haven't used a unique username, so you pop up under twitter (your name is disclosed).

You have a StumbleUpon page which lists your age (27) and your hometown Flxxxxxxxxx, Brazil

You are clearly an Anime Lover.

Facebook has not been involved at all.

Now tell me who his closest friends are, tell me the odds of his being homosexual or belonging to a given political party, and what sort of music, movies and games he likes.

Sure, you could probably find that out by googling; but Facebook makes it significantly easier.

Saying that Facebook hasn't changed our privacy is like saying that firearms haven't changed the face of war. I mean, it just puts metal through your body just like a bow and arrows.

Woah there on the hyperbole! Using a war analogy is not the same as being correct: it breaks down too easily and ends up silly. Do you really care if you're shot with an arrow or a bullet if you are still killed??

I also don't want to turn gldalmaso into some sort of cruel hamster to argue a point. Suffice to say the poor guys twitter feed is completely open. You or I could easily deduce all the answers to your questions based on his past tweets and followers.

If he didn't use twitter, then I could use blog comments.
