I was thinking this after seeing a video that went viral of an American father punishing his teenager by posting a video reply to a Facebook rant about her parents she had done. It didn't take long for people to find his own Facebook page and phone number, etc. While most people were supportive of the father in comments, there were a few people who called the police and child services thinking he was going to harm his kid. He got so many phone calls, he just turned off his phone. He ended up saying if people who knew him wanted to get a hold of him, they knew his email address.
Not that this is particularly unique. Viral videos and posts happen all the time. Basically everyone who's had a Tosh.0 Web Redemption unexpectedly found themselves in the spotlight for something they didn't intend to have thousands (or millions) of people see.
If people were to try and dig up info on me, the most obvious source would be this blog. It's not private and anyone who finds it can read everything. The only people who visit are friends and family, for the most part, and I write my posts expecting that to be my audience. I've been careful not to share things like my address and phone number, but I do recall posting what my personal email address is (after buying my awesome domain). There's other sources of me out there like Twitter (which again is not private), Google + (which no one uses, so no worries there) and the big one... Facebook.
I've been pretty careful to make sure my privacy settings for everything on Facebook are "Friends Only" and that the barest minimum is shared publicly. But every time they change their layout, I find myself having to go through everything again, just to be sure. This latest change to "Timelines" is making it difficult for me to share exactly how I want to share. But I digress.
Anyway, this has motivated me to start going through my online presence and make sure it's "presentable". Just in case the worst (or best) thing happens.
