Common sense didn't come into play, I guess. I don't want to speculate on what motivated this man, but it could have been a very simple example of thinking "hey, I could blog about this!" and then not considering the ramifications of it. Anyone presented with information like this who has a blog has to engage that editorial mindset and stop themselves. That didn't happen here, apparently.
The other thing that struck me was--what if only his mother read his blog? I have four or five blogs like that right now. That's the life, though. That's what blogging really is. You're staggering around, confused, and there's nothing worth reacting to, and no one looks at your stuff.
No, I wouldn't do what this fellow did. I am thankful for what few brain cells and editorial considerations I have.
