Did you take a look at the new privacy settings on your Facebook account?

Yes.

What do you think of them – are they a step forward into allowing more user autonomy and privacy or are they worse than the old privacy settings or even not any different?

They are almost exactly the same.... But they do look clearer.

What impact can these settings have on your Facebook usage?

Non.

Are you OK with disclosing any private information on your Facebook account or have you started to think of being less open on Facebook and disclose less personal stuff?

I have multiple accounts on Facebook, for different groups of "Friends" ... The word "private information" could mean anything... I wouldn't write that I hate my boss, or that I had a fight with my wife on FB, it doesn't belong online (even if it was labeled as Private).

p.s. Why are you asking these questions? I don't think ICTQatar can do anything about Facebook...
