bloody hell, everyone is so damn paranoid... "They" are not out to get us. "They" couldn't organise a piss up in a brewery... as demonstrated by the (North) American government falling apart this week.
Depends on your life needs.
It is not a great thing to have, if you need a security clearance, with much of that, it isn't so much YOU, but who you associate with, and with friends of friends of friends like people seem to gather on FB, you might get some bad apples that you didn't even directly link to, but it can hurt you.
Also, recent stories have come to light about credit ratings....they are going to social media, and looking to see how your friends are and if you have some deadbeat friends, they have it in their algorithms to lower your score with the assumption that you might be more of a credit risk if you associate with people that are credit risks.
I do databases, and information gathering for a living. Trust me, I *know* the value of aggregated data and what it can do to paint a picture for various uses on places, things and people
Even if you're not concerned about govt. looking at this data....this information is being sold off to any corporation or private entity that has the money for whatever they want to do with it.
I dunno...I just grew up valuing my privacy. I've been on the internet and the web since about '92, and even back then in its infancy, people's mantra was to not give out too much personal info and stay as anonymous as possible.
I know it is almost
impossible to have full privacy today unless you live in a shack in the mountains cut off from everyone else. But, I'll be d@mned if I'm going to voluntarily hand over everything there is to know about me to anyone or any company.
I'll put what I need out there for business, but I want to keep as much of my personal data off as many databases as I possibly can.
That's my $0.02,
