Well... considering I'm a writer and I write autobiographical stuff on sex, relationships, adventures, drugs, exes (no names, nothing identifying), my childhood etc... that can be found in my book and on my blog - I kinda don't have much expectation of privacy. But I made that choice.
Do I care? When I got a letter saying "your book has now been accepted by Barnes&Nobles and WH Smith..." I have to say I blanched a bit. There's some seriously graphic sex I've had in it... then I just thought "fuck it. I write. this is what I write. does it actually affect me if people know I'm multi orgasmic? no. not really." What it does do is leave me open for assholes to take pot shots at me, send me weird emails, call me names (some of the people I know on an english lezzo board HATE me cause I'm very open about sex and talking about it. They think it's boring and I must be mental/seeking attention mental... etc. So I do leave myself open for some pretty venomous asshole remarks, emails, IMs etc. I've had three stalkers and people send me all kinds of weird crap like porn and bizzare requests that I help them have anal sex with their friend. That one was from a girl I had asked out on a date. She found my book, read it then text me and said that she was round her mates and was interested in having anal sex with her but unsure of how to go about it.
I told her "use an oven glove" then blocked her
So being public with private things does bring out the annoying in some people. But the choice I have is to work under a pen name - which I do

- and keep my real last name so when I go into massage therapy, that will remain different.
Plus my name on face book isn't mine.

it's my pen name.
I also have an entirely different name for my other job.
I think it's easier to compartmentalise one's life with different names....
