CNN has an interesting piece on bloggers "coming out".
I don't reveal my real name on this blog. I don't post pictures of myself, or my daughter. I have a few reasons why, my employer freaked out when I mentioned work on my Facebook account (specifically when after a hard had I mentioned I had been humiliated. I had been.) I am not "out" as a pagan in most aspects of my life. I don't hide it, I just also don't flaunt it.
While I wouldn't care all that much if someone came on here and said who I was, I would be pissed that I would get fired over it. On the internet you can not express an honest opinion if you expect to keep a job. It's a shame, since you can go anywhere else and bash the hell out of people, but you can't say it on the internet.
This is an evolving new culture, and I really hope we get the kinks out of this. I'm sure we can work it all out, but in teh mean time it's useful to read things like the stories above and remember what happens when you get outed.
