I don't think it's really useful to treat all Facebook accounts as equal. There's a difference between having a profile set to "friends only" with only your family and a few close friends able to view it and a profile with everything public or having 1,000 strangers added as friends or letting every fly-by-night game company have full access. Having a Facebook account tells you absolutely nothing about how much privacy is being lost or what kind of person they are. As with most things in life, it's a subtle issue.
Absolutely. I voted for the "plenty of accounts, fake names and photos" option (though I only have the one account, it's the fake name and photo that I voted for). The reason I have the account is solely to follow other accounts (organisations, mostly, but a few individuals - most of my family and friends are Facebook-phobic).
It does never cease to amaze me the degree to which many (most...) Facebook users are prepared to give up their privacy. But that doesn't negate the value for me, or mean that all Facebook users are so naive.
