Many years ago (can't remember how many, but I know it was more than 11), some genuine friends of mine started signing up on facebook and I started getting the auto-generated "Todd wants you to join him on facebook" emails. And they annoyed me. Couldn't help but think of how many pseudo-strangers that I've contacted once or twice for work or school or whatever via email that would get the same BS message if I signed up. So I never did.
Fast forward several years and I found myself in the (local) media spotlight for something I invented. Suddenly found myself to be the "belle of the ball" but I wanted to still control the release of the proprietary information regarding my device. Luckily I had been very careful regarding personal information and technical information. Then I noticed weird traffic/navigation info in my web logs. Searches that ended up at my site but from originating from facebook? What the?
Then it hit me. A particular reporter with a local paper had been VERY aggressive. One of the things she said to me was, and I quote: "unless you show us how it works we're going to blackball you." Which I found tremendously amusing because I didn't ask for their attention/help in the first place. After I told her that she could go pound sand because she didn't intimidate me, that's when the facebook searches started. It then all made sense: that reporter tried to find anything (dirt most likely) on me, and facebook was her start and end when it came to a search.
Since then I've noticed that any and every person in the news - from victims of crime to alleged perpetrators of it to business owners, etc - if they're in the news, chances are the photo of them, details of their private lives, you name it - all was mined from facebook.
And the fools put it there for everyone to see.
I'm going to do my very best to ensure that my kids stay the hell off of it too.
