I used to keep a blog about our life living aboard our sailboat with our son. We started cruising with him when he was 6 months old, and I documented everything that we experienced -- the good and the bad. We had lots of people following our journey, but eventually, the amount of criticism that we received because of our cruising lifestyle became emotionally overwhelming and damaging for me. People had actually started stalking us. It was nuts. So, I stopped the blog. Lesson learned.
Over the years, I've met many other sailors who keep cruising blogs -- many with kids. Based on my experience, I always secretly cringed inside when I'd read their blogs, hoping that they never had to experience what we did -- that is, until our friends and their kids were rescued in the middle of the Pacific by the U.S. Navy, and had their every parenting decision become the subject of a national debate (including a story on the front page of the NYT and on several morning news shows). You don't even want to know the horrific things trolls posted on their blog or emailed to them -- telling them that they wished they had died/sunk to bottom of the sea with their boat/home, what abusive, selfish a-holes they are, how CPS should take their kids away, etc -- and those are some of the mild ones. And yes, reporters and other nosey Parkers went back through every single blog post written and picked them apart/distorted them. Even if pseudonyms had been used, none of it would have remained anonymous in this digital age. It was all put out there for public consumption, and when the sh*t hit the fan, the public ate it up.
I use my kids' real names here, but I'd never again put anything about them out on the Interwebs that I wouldn't mind the whole world knowing, including their future employers.
