Sometimes it's necessary to avoid controversy because of work situations or personal matters. Here is where having a pseudonym, even an "open" one like mine on this blog, is very handy. My semi-anonymous status served me well when I worked as an educator at Kulani Correctional Facility. On an island, this need to keep somewhat below the radar becomes important, although it's not the concern now that it was when I was working.
I use my real name on Facebook, though, as per the rules and also on Twitter, where it's not necessary. Anyone can open a Twitter account. You have to provide an e-mail, but opening up one under a pseudonym is easy enough.
Some people here have gotten into an awful mess because they were too open and frank about themselves on social media and on their blogs, putting up things about politics and family and so on that got them into trouble. Once that stuff is out there, it's almost impossible to expunge it. On the other hand, timidly avoiding controversy makes for a bland and meaningless "why bother" internet presence.
I remain happily outspoken in this very small space I call my own. But if certain people believe they can't express opinions for work-related reasons, an alias is not a bad idea. I don't presume to understand what the stakes may be for others.
Have we ceded freedom of speech to the crazies like Borden while being intimidated about exercising our own first amendment rights? Well, our completely undemocratic work environments have given employers a lot of rights over employees that they would not have in fairer and more open circumstances. And that keeps people mum. I know it did me, to some extent.
