It's not just someone who might produce technology who has to be careful; it's everyone. Something I wrote in this explicitly personal blog was used to gain leverage against my employer. After that, I went through a great deal of soul searching about whether I should continue to write in my own name. It would have been much easier to write anonymously, as many do. I decided that the risk was outweighed by the beneficial discipline (and terror) of writing under my own name.
Forgotten indescretions have always had the power to come haunting. The difference today is that they're so indestructible. Digital posts are backed up and cached and copied and never go away (except for the ones you'd like to keep, which are governed by Murphy's Law and disappear without a trace). As I said my post about Miranda Murphy, the following rules apply:
Everything you say digitally will be remembered, and can be used against you.Caveat auctor!
If something you say can be misinterpreted, it will.
