I don't show my face because of my job. I just work in a position where even viewing this site would probably result in my being dismissed. Yeah, yeah, yeah, I know the old line, "Well if 'they' see you here, then 'they' are just as much at fault", but that's not always how things play out in real life. 'They' could always counter that they had an anonymous source, etc. Whatever argument that I could come up with, it would be irrelevant after I'd been fired. It's also a field where once you're labeled in any way, even if it's later disproved, you're still stuck with that label. So, even though I have met some people from here in person, I typically keep most of my information rather private.
