Was it Yes or No that surprised you?
Less "yes" than I expected. It increased some since I posted, but the current 38% is still rather low. I've either overestimated the usage in the general population, or underestimated the avoidance by techies.
All that mundane stuff of everyday life isn't interesting to ME, why the hell should it be interesting to anyone else?
Probably, the people who post this stuff do find it interesting to read other people's daily activities.
The order of operations math problems particularly infuriate me,
What's that?
I tried to decypher my wifes Facebook page once but to me it just looks like this:
Modern art?
Is it only me that's a little disturbed by stuff like this?
The poll says you're not the only one.
Facebook cannot share anything that you did not put there in the first place. If any critical detail of your life is leaked - it is your fault.
Technically, perhaps. But many people are unaware of how it works, or of the implications, or are gullible, and Facebook is like a slick conman that's hell-bent on collecting your data and metadata, and maybe also on triggering "involvement". There are probably defaults that expose information you're unaware of, Facebook "apps" that get permissions you didn't expect, and so on. Add to that phone apps, with their own set of shoddy permissions, that use Facebook interfaces or auto-submit stuff to it, and you get a whole lot of attack/exposure surface. Also, shared by whom? Your own info can be shared by someone else on Facebook, also inadvertently.
Some anecdotes:
A friend recently asked me to check a problem related to something on Facebook, so I had some recent FB exposure. I found someplace where FB asks you to fill in details such as linking/identifying your family members: parents, grandparents, siblings, etc.
I've received an SMS from Facebook offering me to look at photos of a person I've talked to over the phone just a handful of times in a professional context.
A 2nd hand story: a friend told me he encountered people who name-tag faces in photos on their account.
